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.

Each land you sacrifice while casting Frostfire Hulk pays for {1}.
Frostfire Hulk enters 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.)

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.
