Typically I play a tourney deck, but I make "stupid" decisions while playing it.
e.g. I was playing Donphan. Fully charged Donphan with 30 hp left, another Donphan on bench. Had a Warp Point. E-belt, and seeker in hand. I play e-belt on the active and hit for a knockout, then get hit by his powered up something (can't remember what it was) to give him 2 prizes. I didn't bother with the WP, Seeker, Donphan drop and carry on as I would've normally because he was new and still learning to play with a modified theme deck. I still won in the end, but he only had 1 prize left. It let him feel good for almost beating me but gave him a goal to come back and actually beat me next time.
