Hapatra, the Desert Frost

When Tinybones enters, each opponent discards a card. Whenever a player discards one or more cards, Tinybones deals 1 damage to each opponent.

Whenever a creature you control with power 4 or greater enters, draw a card. +2: Untap up to two target lands. −3: Create a 4/4 green Beast creature token with trample. −4: Until your next turn, whenever one or more creatures attack one of your opponents, those creatures get +2/+2 and gain trample until end of turn.

Reach Whenever you gain life, put two +1/+1 counters on Titanbones. When you discard this card, you gain 3 life.

Whenever another creature or planeswalker you control enters, mill two cards. Exhaust — 5B: Return target creature or planeswalker card from your graveyard to the battlefield. Put a +1/+1 counter on Liliana. Activate only as a sorcery. (Activate each exhaust ability only once.)

+1: Surveil 1. If you put a noncreature, nonland card into your graveyard this way, put that card into your hand. +1: Add U. Spend this mana only to cast a noncreature spell. −X: Tap target artifact or creature. Put X stun counters on it. −6: You get an emblem with "Whenever you cast a spell, draw a card."

Haste When this creature enters, target instant or sorcery card in your graveyard gains flashback until end of turn. The flashback cost is equal to its mana cost. (You may cast that card from your graveyard for its flashback cost. Then exile it.)

Haste When this creature enters, creatures you control gain trample and get +X/+0 until end of turn, where X is the number of artifacts you control.

At the beginning of your upkeep, if this creature isn't prepared, it becomes prepared. 2: Put target card from your graveyard on the bottom of your library.
