Haste Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)

Prowess If a source you control would deal noncombat damage to a creature an opponent controls, put that many -1/-1 counters on that creature instead.

Choose one — • Boros Charm deals 4 damage to target player or planeswalker. • Permanents you control gain indestructible until end of turn. • Target creature gains double strike until end of turn.

Lightning Helix deals 3 damage to any target and you gain 3 life.

Play with Fire deals 2 damage to any target. If a player is dealt damage this way, scry 1. (Look at the top card of your library. You may put that card on the bottom of your library.)

{T}: Add {C}. {T}: Add {R} or {W}. Battlefield Forge deals 1 damage to you.

If you control two or more other lands, Den of the Bugbear enters the battlefield tapped. {T}: Add {R}. {3}{R}: Until end of turn, Den of the Bugbear becomes a 3/2 red Goblin creature with "Whenever this creature attacks, create a 1/1 red Goblin creature token that's tapped and attacking." It's still a land.

Inspiring Vantage enters the battlefield tapped unless you control two or fewer other lands. {T}: Add {R} or {W}.
