Giratina trio?

It has already been duoed, so yes, trio should be relatively easy.

We had 10 beat Dragon Claw in 100 sec, plus one was my 3 y/o and some other average players. Trio should be ok.

My considerably not optimized team (1 Rayquaza who hadn't even hit his last break point, one with two left to hit, and some miscellaneous dragons) would just barely miss the trio after revive time is included, so for a serious trainer with more than one decent Ray, trio should be easy-peasy-lemon-squeezy.
