We've gotten a couple of leaks from Battle Pack 3, ahead of the set's official release next Friday (August 1). Check them out:
Dark / Level 6 / Dinosaur / 1200 / 2400
During your opponent's turn, at damage calculation, if this card is in your Graveyard: You can pay 1000 LP; Special Summon it, and if you do, you take no battle damage from the battle, and banish this card when it leaves the field (this is a Quick Effect). You can only use this effect of "Stegocyber" once per turn.
Equip only to a Normal Summoned/Set monster. It gains 1000 ATK. You take no battle damage from attacks involving it.
Activate this card by declaring 1 Monster Type and 1 Attribute; Special Summon this card as a Normal Monster (Level 4 / ATK 1800 / DEF 1000) with that Type and Attribute. (This card is also still a Trap Card.)
Banish 2 monsters from your Graveyard, then target 1 face-up Attack Position monster on the field; its ATK becomes 0 until the end of this turn.
07/25/14 Update: Four more World Premieres were leaked today, as well as confirmation of Ghosts From the Past's effect, which you can see corrected above. Now we've got nine out of the ten total, and we're just waiting for one more Trap Card.
Fire / Level 2 / Pyro / 200 / 200
During either player’s Damage Step, when a face-up monster you control
is attacking or being attacked: You can send this card from your hand to
the Graveyard; that monster gains 300 ATK until the end of this turn.
Look at up to 5 cards from the top of your Deck, then place them on the
top of the Deck in any order. You can Tribute Summon 1 monster in
addition to your Normal Summon/Set this turn. (You can only gain this
effect once per turn.)
If you control only 1 face-up monster; until the end of this turn, it
gains ATK equal to the ATK of the monster your opponent currently
controls with the lowest ATK (your choice, if tied).
Activate this card by declaring 1 Monster Type and 1 Attribute; Special
Summon this card as a Normal Monster (Level 4/ATK 0/DEF 2200) with that
Type and Attribute. (This card is also still a Trap Card.)
I'll probably publish a quick review of these cards once the last one has been revealed. Until then, thanks for reading!
07/29/14 Update: The last one!
Boy is it depressing for this card to be saved for last...
Target 1 face-up monster you control; it gains 700 ATK until the end of this turn.
At least the artwork is epic... Reviews will be coming up sometime soon!
