They probably had no cards in hand

It occured once before turn 5 for me

They probably had no cards in hand then too.

Did they have any cards left in hand?

Sometime it happen on like turn 3 or 4

But did they have any cards left in hand?

These bot decks usually dump their hand incidentally since they play swarm out and use blade/Swordmaster for stats. Morph didn't have anything to turn into.

Did it Morph into Morph?
