Shapeshifter is brutally buggy, it has:

- Shapeshifter card bugs (several, mostly related to the "free" shapeshifter it sometimes gets in adventure mode)
- Drafna's Restoration bug (causes the player to instantly get decked somehow)
- Clockwork bug (causes clockwork creatures to remain tapped down indefinitely after one attack)
- Can discard basic lands on turn one instead of playing any
- Can trigger the "invisible card" crash
- Has limited AI for primal clay
- Plays Mana Vault on top of everything which it can't untap and which will keep pinging it indefinitely
- EDIT: Also add Transmute Artifact to the list, the AI can get the invisible card crash bug by fetcihng something expensive with it and not being able to pay the cost.


Can the offending cards be replaced for sake of playability before the issues are adressed?

- 1 X Clockwork Avian
- 1 X Clockwork Beast
- 1 X Drafna's Restoration
- 3 X Shapeshifter
and possibly: - 4 X primal Clay
-? X of Transmute Artifact

Just replacing them with less, well, shapeshifty artifacts like Gold-Forged Sentinel or Su-Chi and, really, anything at all and replacing drafna's restoration with whatever at all would help a lot. The deck would lose flavor but it's just hopelessly bugged ATM. Primal Clay doesn't have to be replaced, but since it always casts it as a 2/2 flier, giving it an actual 2/2 flier with more than just flying would be good for it.

- Mana Vault can generally be replaced with Grim Monolith if it's available.

Also if it's default starting shapeshifter power could be disabled or made to give it something else it would also help. It's bugged to occasionally just die immediately, and the AI won't even attempt to change it's stats (or the stats of it's clones from copy artifact)

It's quite annoying because the deck has 2 potential crash bugs and appears quite often in dungeons.
