Lovestruck Beast

Lovestruck Beast can't attack unless you control a 1/1 creature.

Heart's Desire

Create a 1/1 white Human creature token. (Then exile this card. You may cast the creature later from exile.)

Whenever Bonecrusher Giant becomes the target of a spell, Bonecrusher Giant deals 2 damage to that spell's controller.

Damage can't be prevented this turn. Stomp deals 2 damage to any target.

Flying, trample
Whenever Decadent Dragon attacks, create a Treasure token.

Exile the top two cards of target opponent's library face down. You may look at and play those cards for as long as they remain exiled.

Whenever you cast an Adventure instant or sorcery spell, copy it. You may choose new targets for the copy.

Whenever you cast a creature spell that has an Adventure, draw a card. (It doesn't need to have gone on the adventure first.)
