I was playing in PvP 1 when my opponent timed out after one turn each. On the next turn by the AI, I believe I saw a grabboid be played, attack, evolve and then attack again as a shreiker all in one turn. I was kind of only half paying attention but I can see no other explanation.
Turn by turn of what happened:
Opponent won Toss.
Opponent turn 1 - Plays 3 stone pillars and ends turn.
My turn 1 - Plays spark, immolation and destroyer and ends turn. Deals 5 damage.
Opponent turn 2 - Times out and is taken over by AI.
AI (Opponent) turn 2 - Plays grabboid, grabboid attacks? , evolves grabboid in shrieker, plays stone pillar and ends turn. Deal 8 damage (10 in total).
The rest of the game played out as normal except for that one turn. No idea.
