add a giant rat, which lets you summon a dream clown /blade rabbit upon destruction, if stumbling is out the attacking monster is bye bye....
also "tragedy" is a great card in this deck (works for me) as you can chain it to any time your opponents monster shit to def, and destroy all def on their field.
optional combo (which is kinda risky and builds up space, so it can hinder you in a tight spot) is having dark mirror force, as it can be chained to by "Zero gravity" or "NO ENTRY!" and remove all (former) atk position monsters your opponent Ctrl from play.
but if i where you i'd skip on the reinforcement, as its only target is don and he is a "relatively" weak monster.....
but i haven't had any real competition, so my word might not be any good XD
