Forum:Dragon's Mirror Combo

Hello I've got a query on the effectiveness of D. Tribe over DNA Surgery.

The Situation: It's my turn and I've summoned a D.D Warrior Lady on the field. My opponent then activates the spell Book of Moon flipping her face down.

Now, in my hand is Dragon's mirror and my face down trap card is D. Tribe. Alongside this I have four dragon monsters in my graveyard.

The Question: Can I activate my trap card D. Tribe turning "all monsters on my side of the field" into dragons and then activate my Dragon's Mirror spell to fusion summon Five-Headed Dragon from my extra Deck?--68.80.142.179 (talk) 06:52, May 28, 2013 (UTC)
