So is a level 11 Light Synchro monster and needs: 1 Tuner + 1 or more non-Tuner monsters to get it out and it's effect is: Must be Synchro Summoned, and cannot be Special Summoned by other ways. This card's Synchro Summon cannot be negated. When Synchro Summoned, cards and effects cannot be activated. If this card attacks, it is unaffected by other card effects until the end of the Damage Step. So yeah it is a pretty cool card and i think it is gonna get pretty pricey and it is just cool to see the Synchro's again!
Brotherhood of the Fire fist - Rooster:
It is a level 3 Fire monster and it's effect is: When this card is Special Summoned by the effect of a "Fire Fist" monster: You can add 1 "Fire Fist" monster from your Deck to your hand. You can only use this effect of "Brotherhood of the Fire Fist - Rooster" once per turn. Once per turn: You can send 1 face-up "Fire Formation" Spell/Trap Card you control to the Graveyard; Set 1 "Fire Formation" Spell/Trap Card directly from your Deck. So i think this card is pretty OP. And i think it will see alot of plays a specialy in the Fire fist decks. But i fear that it will get hit on the ban list, but still a awesome card!
Number 66: Master Key Beetle:
This is a Rank 4 Dark Xyz and needs 2 level 4 Dark Monsters to summon. It's effect is: Once per turn: You can detach 1 Xyz Material from this card, then target 1 card you control, except this card; while this card is face-up on the field, that card(s) cannot be destroyed by card effects. If this face-up card on the field would be destroyed, you can send one of its targets to the Graveyard instead. This card is absolutely amazing. This card can just make such good defensive plays and has 2500 atk as well.
