Card of the week (2/19/13)

Number 107: Galaxy-eyes Tachyon dragon.
Effect:
2 Level 8 monsters
Once per turn, at the start of your Battle Phase: You can detach 1 Xyz Material from this card; negate the effects on the field of all other face-up monsters currently on the field, and if you do, have their ATKs and DEFs become their original ATKs and DEFs.
If an opponent's card effect activates during a Battle Phase of a turn that effect is used, this card gains 1000 ATK until the end of that Battle Phase (each time), and this card can attack twice during each Battle Phase that turn.
