Shift the Card

All good points. I was thinking that 7 mana for the first -3/-3 and BBB for the destroy was balanced, but everything should definitely have been sorcery speed (except maybe the destroy, if I wanted it to be splashier).

Heart of the Wilds 5RG
Enchantment
Whenever a creature dies, exile it.
Whenever a player casts a creature spell, for each creature card exiled with ~, that player may create a token that is a copy of that card. Those tokens have haste. Exile them at end of turn.

Next: Futureshift Stangg

Up: The only thing I would change was to make it a Golem Warrior.




Next: An Alternate Land Equilibrium

Up: Fun little shift with land hate. Given how powerful lands are these days, this would fit in well in most blue decks.




Planeshift: Ancient Grudge
(Planeshift: make this card an exact copy of the previous card, except it is now in a new color, with new flavor, and all that. Be sure to include flavortext, otherwise it would be boring. One of these cards in real life is Piracy Charm, planeshifted from funeral charm.)

Up: The reason I don’t like Planeshifting as part of this game is because it’s supposed to be the exact same card, just in another color. Your design was interesting, so I’m going to treat it like a Timeshift.
That being said, Nature’s Resolve is very overpowered. 1G for destroying an artifact with an upside is the rate we get, but this flashback is too good an upside. Shatterstorm is a sorcery for 4 and By Force is a sorcery that costs more for each artifact, but yours is 3 mana, at instant speed, to destroy all artifacts without spending a card.
Your card as a sorcery, with flashback for 5 or 6, would be much more balanced.

Draining Lightning RR
Instant
Draining Lightning deals 4 damage to target creature. When that creature dies this turn, add an amount of R equal to that creature’s converted mana cost.

Next: Alternate Mundungu (https://scryfall.com/card/vis/132/mundungu)

Up: That ability is slightly undercosted, and to keep with the original card, I would have had the mana be added at the beginning of the next main phase.




Probably a more powerful than the original, but it's in the colors.

Next: Timeshift Crystal Spray

Also, I totally agree that planeshift is wonky right now. I try to avoid giving planeshift challenges, and don't usually consider taking them either.

Card can be modified if it ultinately accomplishes the same effect. ([card]Blastoderm[/card], [card]Calciderm[/card]) If the card is UP/OP/super niche, you're allowed to rebalance or tweak it (e.g. Turning [card]Melting[/card] into a snow based [card]Cyrptolith Rite[/card]).

Edit: Looks like card tags don't work on mobile, rip.

Up: (Mundungu)
I really like the flavor you created, the naming is a little corny but I probably couldn't come up with much better in the short term for a Visions card myself.

Next:
Alternate Garruk Wildspeaker (you can make a new planeswalker it doesn't have to be Garruk).

UP: Simple but effective is my favorite thing about classic Garruk and I feel like you've captured that perfectly here.

Hibernation Wards
Enchantment
You can't gain life and creatures you control can't attack.
Prevent all combat damage that would be dealt to you.
Frozen in sleep, or frozen in time?

I figured that if I was going to have to give the card a color, I might as well tweak the type to match that color as well.

Next: Futureshift Dragonsoul Knight.

Up: I think Bring to Pasture is too efficient, even for a 2-color card, but the ovinization (that’s probably not a word) is very clear.

Wren’s Run Alpha
Creature — Wolf Warrior
You may champion a Wolf (RT)
At the beginning of your upkeep, create a 2/2 green Wolf creature token. Then, if Master of the Pack championed a creature, Wolves you control gain deathtouch until end of turn.
4/4

Next: Use our fancy new Planeshift to fix Sorrow’s Path

Up: What a way to show off the new Planeshift. My only problem is with Fog of Sorrow. I assume the second ability should read "their controller's next turn"? As written, they can just never attack again, unless they somehow attack on someone else's turn.




Thought about doing a land for this one (the history buffs among you might guess why), but after finding that quote from King Solomon's actual successor, I couldn't not make him into a card. I think you see why.

Next: Alternate Providence

As accurate as Rehoboam may be, I do wonder how much of a pie break it is. I do like the idea of a Solomon-themed set, though...

Up: A zero mana 10 damage spell in the wrong hands, I'd say. RDW would probably try and force this into its decks for the sheer value alone - consider taking notes from Chancellor of the Dross and instead having the first effect be a small lifeloss effect, and the second making the opponent lose 10 life.

Liked this concept so much I ended up making a render for it:



Platinum Walker
Creature - Alien Horror
Menace
Whenever an opponent would win the game, they instead lose the game.
4/4
One of these days I'd like to do a War of the Worlds themed set.

Next: Planeshift Mountain, nah, just kidding. Planeshift Personal Sanctuary.

Up: (Mountain Sanctuary) Nice, although I would probably remove the life gain prevention as it not only doesn't match the original card but is redundant if prevented only during your turn (most dangerous life gain is sorcery speed).



Next: Mental exercise futureshift Exhume, or if you really can't come up with that then Timeshift it.
