This spell can't be countered.
When Frostbreath Dragon enters, tap target creature. It doesn't untap during its controller's next untap step.
Whenever Frostbreath Dragon becomes the target of a spell or ability, counter it unless its controller pays {2} and discards a card.

This spell costs {4} less to cast if a player attacked with four or more creatures this turn.
End the turn.

As an additional cost to cast this spell, you may pay {3}{W}.
Choose a nonland permanent type. Destroy all permanents of the chosen type. If this spell's additional cost was paid, destroy all permanents of the chosen type you don't control instead.

Create three 1/1 green Saproling creature tokens.

When Fungal Whomper enters, you gain 4 life.
When Fungal Whomper leaves the battlefield, germinate four times. (To germinate, put a +1/+1 counter on a creature or create a 1/1 green Saproling creature token.)

Gain control of target creature until end of turn. Untap that creature. Until end of turn, it gets +1/+0 and gains haste.

If a source you control would deal noncombat damage, it deals double that damage instead.

First strike
Persist (When this creature dies, if it had no -1/-1 counters on it, return it to the battlefield under its owner's control with a -1/-1 counter on it.)
Creatures you control with -1/-1 counters on them have double strike.

Flying
Whenever a player casts a spell, if it isn't that player's main phase, each of their opponents may draw a card.

Flying
Whenever you cast a creature spell, creatures you control get +1/+1 until end of turn.
Whenever you cast a noncreature spell, create a 2/2 red and white Cat Knight creature token.

Trample
Cycling {2} ({2}, Discard this card: Draw a card.)

Vigilance
Melee (Whenever this creature attacks, it gets +1/+1 until end of turn for each opponent you attacked this combat.)
Whenever an opponent attacks you, create a tapped 1/1 white Soldier creature token with melee. Exile that token at the beginning of your next end step.

Defender (This creature can't attack.)
Hexproof (This creature can't be the target of spells or abilities your opponents control.)

At the beginning of your upkeep, mill two cards.
{1}{B}{B}: Until end of turn, Gaunt Abnormality becomes a copy of target creature card in your graveyard, except it's 3/3.

[+1]: Creatures you control get +0/+1 until your next upkeep. Untap those creatures.
[–2]: Put target tapped creature into its owner's library third from the top.
[–7]: You get an emblem with “Whenever a nonland permanent you control is put into a graveyard from the battlefield, each opponent sacrifices a nonland permanent.”

First strike
When Gavis's Dragoons enters, exile another target creature until Gavis's Dragoons leaves the battlefield.
Spells with the same name as the exiled card can't be cast (as long as this creature is on the battlefield).

Pressure {1}{U}{U} (You may cast this spell for its pressure cost if seven or more cards are in your graveyard.)
Draw three cards.

Search your library for three land cards with different names, reveal them, then shuffle. Put one of those cards onto the battlefield, one into your hand, and one into your graveyard.

Motivate 3 (When this creature enters, you may motivate target creature with less power than this by putting three +1/+1 counters on it.)
When General Merthilios motivates a creature, that creature gains first strike, trample, and haste until end of turn.

Draw two cards.
You may cast an instant or sorcery spell with mana value 3 or less from your hand or graveyard without paying its mana cost. If that spell would be put into a graveyard, exile it instead.

This spell costs {1} less to cast for each enchantment you control.
Shuffle, then exile cards from the top of your library until you exile three nonland cards. Cast any number of spells from among cards exiled this way without paying their mana cost, then put the rest onto the bottom of your library in a random order.

Up to two target creatures each get +X/+X until end of turn. They must be blocked this turn if able.

Return target creature card from a graveyard to the battlefield under your control. Post a bounty on that creature. (Put a bounty counter on that creature. It has “When this creature dies, each opponent draws a card” as long as it has a bounty counter on it.)

Trample
When Ghastly Progenitor enters, each opponent reveals their hand. Choose two nonland cards revealed this way. Their owners discard those cards.
