1/3

Still no, but trending in the right direction?

Winterheart Invoker
Snow Creature - Gnome Shaman
Hexproof from nonsnow
: Winterheart Invoker deals 2 damage to ay target.
2/3

it fits!

Criterion guess: Has a 2 at least twice somewhere on the card

Fist of the Nine-Tail
Creature - Fox Monk
Prowess, double strike
2/2

Criterion: Has an activated ability that does not require tapping.

Agitated Pyrohydra
Creature - Hydra (R)
Ravenous (This creature enters the battlefield with X +1/+1 counters on it. If X is 5 or more, draw a card when it enters.)
Haste, trample
: Agitated Pyrohydra gets +2/+0 until end of turn.
1/1

I like the card, but it doesn't fit. And the criterion is wrong.


Another cute design. I'm a sucker for new keywords when they're reasonable. But it doesn't satisfy the criterion and the criterion you shared isn't accurate.

Interesting.

Also, just in case it wasn't clear, ravenous is an official keyword, but from an Universes Beyond product.

Oh, I had no clue about that product. Makes sense, then, that the keyword was reasonable.

Y'all can think a little bit simpler for the criterion, btw.

Criterion: Card is a Shaman?

Deepwood Elder
Creature - Elf Shaman
, : Search your library for an Elf card, reveal it and put it into your hand. If you do, shuffle your library. ~ costs less to activate for each Forest you control.
1/3

ding ding ding!

You're up, SilentTwin!

Geez, hidden in plain sight.

A new criterion is afoot and here is an example card.

Failing Goldmine
Land
~ enters the battlefield tapped with 4 Gold counters.
, remove a Gold counter from ~: Add 2 mana of any color to your mana pool. ~ does not untap during your next untap step.

Sadly no. Cool card though.

Praetors' Womb

Creature - Phyrexian Horror
: Exile target creature. Incubate X, where X is equal to its power. Praetors' Womb doesn't untap during your next untap step.
1/7

Nasty looking guy there, but he doesn't follow the criterion.

Sure why NOT keep with late-night creeptastic cards?

Urban Renewal

Enchantment
Sacrifice a land: Add two mana in any combination of colors. You may play an additional land this turn. Activate this ability only during your turn and only once each turn.
The unguilded residents were, with their homes, compacted into the construction of the new district, a permanent collection of death and agony screaming from the walls of each pristine building. The Golgari, at least, were willing to pay premium rent.

You are an evil, evil person. But nope, doesn't follow the criterion.

Magnus McGilded
Legendary Creature - Human Citizen (R)
At the beginning of your upkeep, create a tapped Treasure token.
Sacrifice a Treasure: You lose 1 life, draw a card, then discard a card.
Sacrifice three Treasures: Gain control of target creature until end of turn. Untap it. It gains haste until end of turn.
Sacrifice a creature and four Treasures: Search your library for up to two cards, put them into your hand, then shuffle.
2/2

Could be a fun antagonist in the other game, but here, it doesn't follow the criterion.
