i know Miragegaogamon is up there for 'stat boost' but i'd go as far as to suggest.
Add 30 more stats to Atk and move 60 from Support and put it equally in defense and HP. The character strikes me as an all round card with his abilities but not excelling at anything in particular, so his very balanced stats reflect that. Or if you want to keep him Support heavy then leave the 30 to HP and keep it on Support. (349 HP, 385 Supp)
