Mecha Phantom Beast
Mecha Phantom Beasts are really efficient at summoning tokens. These tokens are all 0 attack monsters that you can use as tribute to special summon Reptillianne Vaskii. Additionally, Mecha Phantom Beast decks currently lack an effective boss monster, a role which Reptilianne Vaskii can fulfill.
No answer to backrow, no reptilianne naga, slow to set up with gardna (of you draw him, WoD isn't reliable enough, summoning vaskii can be tricky and may require life point dependent skills. IF reptilianne naga is released THEN this will be very good.
and it call be easily destroyed along with all most other Reptilianne cards by a common card called doom donuts... sigh
