Memento {3}{R}{R} (You may cast this from your graveyard for {3}{R}{R}. If you do, put it onto the battlefield transformed after it resolves. Exile it if it would leave the battlefield or not resolve.)

Menace
Whenever Auros, Flame-Cursed attacks, it deals 3 damage to each opponent.

Exile the top two cards of your library. You may play one of them until the end of your next turn.
Motley — If there are five or more names among nonland permanents you control, you may play both of them until the end of your next turn instead.

Each land you sacrifice while casting Frostfire Hulk pays for {1}.
Frostfire Hulk enters the battlefield with a +1/+1 counter for each land card in your graveyard.
Sacrifice Frostfire Hulk: It deals X damage to target creature or planeswalker, where X is the number of +1/+1 counters that were on it. Activate only as a sorcery.

Target opponent may have you draw X cards. If they don't, reveal the top X cards of your library. Hell's Verdict deals damage to that player equal to the total mana value of cards revealed this way.

Inferno Lash deals 2 damage to target creature or planeswalker. When it does, torment that permanent's controller. (They lose 3 life unless they discard a card or sacrifice a nonland permanent.)

Flying, haste
Whenever a nonbasic land becomes tapped, it deals 2 damage to its controller.

Whenever an opponent casts a noncreature spell, create a Treasure token. (They're artifacts with “{T}, Sacrifice this artifact: Add one mana of any color.”)

Haste
Motley — At the beginning of your upkeep, if there are five or more names among nonland permanents you control, Scarletblood Hound deals 3 damage to each opponent.

This spell costs {1} less to cast for each noncreature, nonland permanent you don't control.
When Earthform Pachyderm enters the battlefield, destroy target noncreature, nonland permanent. Its controller creates a 3/3 green Elephant creature token.
