One of the ways you can deal with Tarkir’s own poster boy is a popular card from the previous block: Hero’s Downfall. There’s some nuance to timing this, though. First of all, realize that no matter whether Sarkhan is a not-a-Dragon planeswalker, or a DRAGON!! not-a-planeswalker, he’s still a legal target for Hero’s Downfall because at all times he’s either a planeswalker or a creature. The important part involves the abilities that come alongside his dragonic transformation: if you let the ability resolve, Sarkhan will be indestructible, which means “destroy” effects like Hero’s Downfall can’t touch him. Don’t think you can use a burn spell to reduce his loyalty to 0, either — since DRAGON!! Sarkhan is no longer a planeswalker for the turn, damage-dealing effects won’t reduce his loyalty.
However, if you try either of these methods in response to the +1 ability (after the counter is added, before it resolves), Sarkhan in his still-vulnerable planeswalker form will be swiftly sent to the grave. The ability will still resolve, but with no living Sarkhan to DRAGON!!ify, it will simply fail to do anything.
