Unbendable Pies Breaks

hydraheadhunter
It seems like that it really exists in Ice Age or Legends, besides snow nor stun were born after them.
I like this flavor but in recent view, it is totally breaking the pie.

Idea
Once damage spell was for red and black, and damage redirection is for their enemy color, white.
Now green get often to emit power-based damage spells so the enemy of red-green has a right to access damage redirection.
Also it fits simply with blue image.
The descision you priored Psionic Rifts to the second one was right.
Face damage is not bad, but it requires you a library manipulation to use unless you accept a 40% chance of 0 damage for 4 mana.
Even in an environment where full of strong creature removal spells, I am hard to think this is chosen as a finisher in a control deck.
And the voratility from 0 damage when a land was revealed to an overkill damage when an Eldrazi titan was revealed seems to be red rather than blue.
Also, the "last counter was removed" condition has a problem since if you revealed a land, it is never sacrificed.

vizionarius
It is useless if your opponent doesn't draw an additional card but there are Howling Mine and its cousins.
Preventable the damage with  is worse than Black Vise and its fallowers but it triggers twice if you forced your opponent to draw 2 cards.
It could find its role in some decks and seems to be simply useful in EDH.

Winner: vizionarius.
Blue is the top color of unblockability and unblockable attacker is similar to direct damage to a player.
So I feel damage to player is better than to creature for blue.
I expected a creature damage spell with high persuasiveness comes and break my stereotype.
Idea's one is good, but I feel it should be uncommon or higher rarity so it didn't reach vizionarius' one.
The runner up is Idea, and #ShitpostingOnTheSevens is hydraheadhunter.

Well, blue may not be the color of pumping per se, but it is a color of transformation and setting, so...

It might be true it didn't need to, but the cards I had in mind as I designed it did have it lose all abilities and I do still think it's more in line with the original pongify which outright replaced the creature with a vanilla token.

While white isn't the color for haste, I think rushing in to help your allies is certainly something white really wants to do flavor-wise. I think a way to portray that that functions flavorfully and mechanically for white is twofold:
1.Make it conditional. White can get effects it normally doesn't, like creature destruction, by meeting conditions such as some form of "retribution" or a breach of unwritten rules
2.Instead of a guy going off on his own ahead of the rest, they get 'haste' by joining their allies in the attack.

I'm posting this card as is for now, though I'm unsure on the wording. The problem with trying to get the effect I want to work (where a creature already on the battlefield is allowed to attack but only attack the opponent that damaged you and only alongside this other guy) is that an attack trigger will only go off after attackers have been declared, so letting them attack then wouldn't actually make you able to attack with them. On the other hand, effects that make a creature tap and attack tend to either be of the "they must attack this turn" variety or the ninjutsu variety where they "enter tapped and attacking", but seeing as I don't want to blink the creature that doesn't work either...

Creature -- Human Soldier
First strike
As long as you control a blocked creature, you may cast ~ as though it had flash. If you cast ~ this way, it enters the battlefield in a band with a blocked creature you control tapped and attacking. (Bands are blocked as a group. You divide combat damage among creatures in each of your blocked bands, not the blocking creatures' controllers.)
2/2

Note: I cleaned up banding's reminder text to make it a lot more legible. Since we are not declaring the band upon attacking, and we are not blocking with them here, parts of the reminder could be omitted. 702.22e means that the banding keyword doesn't actually have to be on the creature if we explicitly form the band outside of declaring it through attacking with a creature with banding. I wanted to use "You divide combat damage among creatures in each of your bands, not the defending player," but that wouldn't work in cases where another player somehow gained control of a blocking creature (the player you originally attacked would still be the defending player, but the new controller of the blocking creature would need to assign damage as per 510.1e).

Edit: Updated wording to actually work within the rules. Thank you Glimpse the Cosmos.

Thanks for the win Flo00!

Next, how about some enchantment destruction in red?

Entropy Warp
Instant
The owner of target enchantment, artifact or planeswalker you don't control shuffles it into their library.
That player reveals the top card of their library and if it’s a card that shares a type with the card shuffled into their library, they put it onto the battlefield. If not, they exile it. Repeat this process until a card is put onto the battlefield. Then shuffle the exiled cards back into its owner's library.

Feedback

Idea : I like the route you took for red enchantment destruction, which is through combat, and in stripping the Auras from the blocker. Nice art find! I think it's a little overcosted at 4 mana, and the equip cost is a little steep, especially since it doesn't actually synergize to pump the creature. It's a bit of a niche effect, so would have liked if it was a bit stronger. Since the name suggests that it feasts on spells, I don't think it would break it if it added counters onto itself for enchantments dying, and then added that as power to the equipped creature. That way, you can keep the "feed me" equip cost and have the equipped creature benefit from your own sac. Overall I think this is a neat way that red could have enchantment destruction.

melono : Neat effect! Doesn't outright destroy, but it does put away for some time. It could have the effect of simply getting the same card back if the player only has one card of that type, which is a bit of a point against this, but the effect feels very red. I might have gone with a "noncreature permanent" wording and include lands in the process to get away from explicitly calling enchantments out. The templating for these types of effects is: "...exiles cards from the top of their library until they exile a card that shares a card type with it. They put that card onto the battlefield and shuffle the rest into their library." The only difference will be that in one, the card enters from the library, and in the other, it enters from exile. But it saves on some words.

Edit: Oh, I found this... Wild Magic Surge. You were really close to this one (and it doesn't use the exile wording I have above)! So I guess yours is technically how WotC would do it (your card's name is vastly better...). Will keep my initial post's result though.

moweda : I really like this! It does combine two red effects really well, and makes for a very versatile card! It's very strong ("Thanks for getting your planeswalker to ultimate range... I'll take it and use it on you"). It's a removal AND an extra threat. I think 5 mana is too low for this effect. For mono-red, the cheapest this is for just creatures is Grab the Reins at 7 mana, and you can't even swing with the creature there. These cards are the only ones I found that have something similar. I think for your effect, it would need to be something like ? I really like this kind of solution, though!

Result

The winner is moweda with a clean design that feels like a path WotC would likely take for this type of enchantment solutions for .

Inspired by D&D5e's adjuration wizard's key feature, the arcane ward. It lets your wizard be less squishy by giving them a shield that is replenished by casting spells, the higher the spell slot spent the more it's restored. It's acts essentially as additional hit points and so the version I made for MTG uses counters as virtual life.
