I made a deck with 4 peguses, 10 light pillars, 6 PUs, 10 aether pillars, and mark of air. Went into pvp. I played a peguses, and then dived it, and PUed it before ending my turn. Next turn, I dive the new pegasuses, then PU that one, end turn. Continue. original peguses is 3/2. It dives, I PU it. New one is 6/2. I dive that one, copy it, new one is 12/2. Dive, copy, 24/2. dive, copy, 48/2. I had another PU in my hand, but then I won :\
You could concievably get a 184/2 peguses capable of diving for 368 damage in one turn ^_^
that makes me so happy.
