Card of the Week Contest #447: At the beginning of 2023..

It's not technically in the card itself, but I made a keyword with "At the beginning" so I hope that's allowed.

This might be intentional, but just in case it's not this thing can be a 3 mana emblem with "make a tapped power stone each upkeep"

Well, I was gonna post a treatise on a cycle of monocolor Auras that gave you control over a type of permanent that's most represented in the color of the Aura (like a green Aura that gave you control over a creature), that all had an upkeep cost of 1N, where N was that color (because it really just makes sense that a color whose identity is so tied up with that permanent type would be able to take control of a permanent of that type), but then I came to a design I dreamed up recently, and I just hadda post that, because I'm a validation-craving attention whore:

Arno Coleman, Slacker Evangel 
Legendary Creature--Human Tyranid Cleric Wizard
Whenever a player casts a spell, put a +1/+1 counter on Arno Coleman, Slacker Evangel.
Noncreature spells cost less to cast for each counter on Arno Coleman, Slacker Evangel.
As long as the number of counters on Arno Coleman, Slacker Evangel is five or greater, creature spells cost less to cast for each counter on Arno.
At the beginning of each player’s end step, remove all counters from Arno.
1/2

vizionarius : DAMMIT!!!

Ok, going with a card inspire by quite possibly the greatest moment in World War Z:

Battle of the Catacombs 
Instant
Cast this spell only during combat before attackers are declared.
This spell can’t be countered if there are ten or more creatures on the battlefield.
All creatures gain aggressor until end of turn. (They must attack each combat if able.)
Each creature can block any number of creatures this turn and must block each combat this turn if able.
At the beginning of the next end step, exile each creature that blocked or was blocked this turn.
-----------------------------------------------------------
“ON NE PASSÉ PAS!”

Idea It is as intended. Yes, artifact broken, uninteractive, whatever. But tapped powerstones are REALLY slow, based on my experience. (Not to mention, usually, powerstones are not compatible with control game plan)

If you think it's too imbalanced, I can change it to 4 mana.

Recursive Nightmare
Sorcery
Target player discards a card.
At the beginning of your upkeep, if Recursive Nightmare is in your graveyard, you may discard a card. If you do, return Recursive Nightmare to your hand.

Not sure if this should be instead.

where can i get that card? Is it like an mobile online games? What do I have to do to be able to use it? can anyone guide me? Thank you and have a happy new year everyone.

In case you meant where you get scheme cards: There have been two products featuring them so far: Archenemy and Archenemy: Nicol Bolas. It is meant to be played 3 vs. 1, where the one player (the archemnemy) uses scheme cards that they set in motion at the beginning of their first main phase. You can also play a "normal" game of Magic and give each player a deck of scheme cards (or even do one shared scheme deck).

Slow Burn
Instant
~ deals 2 damage to any target. At the beginning of your next end step, ~ deals 2 damage to that permanent or player.

That's actually an interesting point that never was brought up so far as I know. Guess you're right about rules text, but as flavor text can have a bit of leeway and doesn't have to be 100% correct and/or complete, I think it's fine the way it is still
