How do you get rid of stuffy doll on magic the gathering?

Answer 1

When your Stuffy Doll enters play, you choose one player. If any damage is dealt to Stuffy Doll, then Stuffy Doll deals that much damage to the chosen player.

So if Stuffy Doll is in play, and you use Pyroclasm (deal 2 damage to all creatures) then two damage will be dealt to Stuffy Doll, which in turn will deal 2 damage to the chosen player (Stuffy Doll itself survives because it is indestructable). If it blocks a 6/6 creature, it will take 6 damage and deal 6 damage to the chosen player, etc.

Lastly it has an effect where it can deal 1 damage to itself, which will then be dealt to the chosen player. So even if the opponent isn't doing anything that could damage your Stuffy Doll, you've still got a way for it to be doing something.

Answer 2

Stuffy Doll has the ability Indestructible. Indestructible states that the creature cannot die due to damage or effects that say "destroy". This makes it very hard to deal with, but not impossible. If an indestructible creature has 0 toughness, it still dies. Damage is tracked separately from a creature's toughness. So if you had a spell that gave Stuffy Doll -1/-1 until end of turn, it would die. You could also return Stuffy Doll to its owner's hand or library. That's a common method of temporarily dealing with a card. There are some cards such as Banishing Light that exile cards, which would also work. It's rather uncommon, but if you could find a way to make your opponent sacrifice their Stuffy Doll, that would also kill it.

There are a few other tricky ways to deal with Stuffy Doll. Some spells or abilities can tap an artifact or creature and/or keep it tapped. If you do that, Stuffy Doll can't use its tap ability and it also can't block. Lastly, cards such as Pacifism state that the enchanted creature can't attack or block, so that could give you some valuable time.
