Haste, prowess
Wanderlust — When Spitfireling enters, if you control four or more differently named lands, create two 1/1 red Elemental creature tokens with prowess and haste.

Flying, haste
Erratic (When this creature dies, reveal the top four cards of your library. Put a creature card that costs less than this revealed this way onto the battlefield and the rest on the bottom of your library in any order.)
When Splitflame Phoenix dies, you may pay {R}. If you do, return it to its owner's hand.

When Sporecrowned Scavenger enters, target opponent loses life equal to the number of Insects you control and you gain that much life.

When Spreading Dissent enters, exile all creatures until Spreading Dissent leaves the battlefield.
{X}: Put a random creature card with mana value X exiled with Spreading Dissent onto the battlefield. Any player may activate this ability.

Bloodprice {2}{U} (You may cast this card by sacrificing a creature and paying its bloodprice.)

Voracious 2 (As this enters, you may sacrifice up to two artifacts and/or creatures. This creature enters with that many +1/+1 counters on it.)
Each creature you control with a +1/+1 counter on it has trample.

Vigilance, trample
At the beginning of combat on your turn, put a +1/+1 counter on target legendary creature you control.

Flying
Starbane Elemental's power and toughness are each equal to the number of creatures with flying you control.
When Starbane Elemental enters, destroy all creatures without flying.

Shimmer (Whenever this creature attacks, create a tapped and attacking token that's a copy of it. Exile the token at the beginning of the end step.)
Each other creature you control gets +1/+1 for each creature you control with the same name as it. (A token's name is its creature types unless specified.)

Equipped creature gets +5/+5.
Whenever equipped creature becomes blocked, destroy all other creatures.
Equip {5}

Reveal the top five cards of your library. An opponent separates those cards into two piles. Put one pile into your hand. You may cast a nonland card with mana value 3 or less from the other pile without paying its mana cost, then put that pile into your graveyard.

You may pay {2}{W} and tap an untapped Cleric you control rather than pay this spell's mana cost.
Exile target artifact, creature, or enchantment. You gain life equal to its mana value.

Flying

When Steelcharm Obliterator enters, choose one —
• Put two +1/+1 counters on Steelcharm Obliterator.
• Target creature you control fights another target creature.

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

Exile two target creatures, planeswalkers and/or enchantments, then return one of those cards to the battlefield under its owner's control.

Target creature you control gains indestructible until end of turn. Whenever that creature perseveres this turn, create a 2/2 black Zombie creature token. (A creature perseveres when it survives damage.)

You may pay {1}{R}{R} and tap an untapped Knight you control rather than pay this spell's mana cost.
Target untapped creature you don't control blocks this turn if able. Other creatures can't block this turn.

This spell can't be countered.
Flying
Dominance — Whenever Stormwing Ultrateryx becomes the target of a spell an opponent controls, if you control the creature with the greatest power or tied for the greatest power, counter that spell.

If you would lose the game, instead sacrifice a storied permanent. If you do and your life total is less than 1, it becomes 1.

Flying
When Stratusform Seraph enters, you may return target creature you control to its owner's hand.

When Student of the Crane enters, create a 1/1 white Bird creature token with flying.

Renown 1 (When this creature deals combat damage to a player, if it isn't renowned, put a +1/+1 counter on it and it becomes renowned.)
Whenever a creature you control becomes renowned, you may have it fight target creature you don't control. (Each deals damage equal to its power to the other.)

Flying
{B}, Sacrifice another creature: Draw a card.
