Legendary Creature â Merfolk Shaman
Tishana, Voice of Thunder's power and toughness are each equal to the number of cards in your hand.
You have no maximum hand size.
When Tishana enters the battlefield, draw a card for each creature you control.
The number of creatures you control is counted only as Tishanaâ€™s last ability resolves. If Tishana is still on the battlefield, itâ€™ll count itself.
If Tishana enters the battlefield while you have no cards in hand, it will be put into your graveyard for having 0 toughness before its triggered ability resolves.
Because damage remains marked on a creature until itâ€™s removed as the turn ends, the damage Tishana takes during combat may become lethal if cards leave your hand later in the turn, such as by casting them in your postcombat main phase.
