Using welcome to the fold on Emerge creatures (tested with lashweed lurker and elder deep fiend) seems to produce several interesting visual bugs (which don’t crash the game, fortunately).
- After player steals an emerge creature, creatures played in the “stolen” spot will be invisible, but do actually exist.
- Invisible cards produce all the same animations that a normal card produces, and can be targetted by targetted spells/effects. Upon doing so, the card will turn totally black except during the AI’s turn.
- Attempting to steal this black card produces a third visual bug: the card operates as if it was on the correct side of the field, but visually remains on the opponent’s side. I was not able to test if it added to the 3 creature stack limit.
Basically be wary of emerge cards; guessing the visual bugs aren’t limited and if you’re not paying attention during QB or the event or what have you, you could get burnt pretty badly.
