Can i use a ability that causes a card to tap when that card enters the battlefield?
Asked by McSween7 10 years ago
So I've built a deck with tokens and I have included two cards:
Both have abilities that force them to tap, but can i use these abilities on the turn they enter the battlefield? Or does summoning sickness affect them?

Side note: for Skirsdag High Priest's ability, the other creatures you tap as an additional cost can have summoning sickness. It's not their ability with the 
symbol that you're activating, so it's okay to tap them for it.

Boza thanks, so I can use Thraben Doomsayer 's ability as soon as he enters the battlefield?

No, you cannot. Though if you have 5 or less life, the second ability will be "live" as soon as the creature enters the battlefield.

No, summonning sickness prevents tapping of a creature, unless you have controlled it since the start of your most recent turn.
