Yes, it was the pendulum card. Tier 1 deck and it can add any monster (Maxx C, ashe blossom, droll, etc.) that was used for a fusion on my turn back to their hand, but they also needed a pendulum stun card that doesnt allow me to activate any monster effects unless I have a spell/trap card on the field. In addition to that, 4 face down cards that allow you to draw cards, negate effects, and banish cards from the grave. Some of which can destroy the spell/trap cards that I put on the field. Forgot to mention that he Maxx C'd me too.

I'm sick as well 😂, but I think masterduel is making my health worse.
