Begin Anew+TGT+Ibuki=Hot Sauce (of course, TGT isn't always going to be there if I'm blowing the field up)
Recall that part of what made Ibuki so janky outside of Higher Calibur and Suzaku in B2 was that, in a normal Ibuki deck, she could play Infiltrating on Turn 1 with no chance of failing unless the check gets hacked by your opponent. Well, Begin Anew will serve as the proverbial replacement for that in Block 3. Albeit it won't be nearly as free (especially with 3 two checks in the deck), it's still a pretty sound strategy, if you ask me.
Evil Plans is main-decked because A) It's a 5 Check and B) You're kidding yourself BIG TIME if you think you'll never run into BRT anymore at a major competition. I can guarantee that it'll happen in at least 2 of the 6 matches a player would play normally, and probably more than half of the top cut will be packing it. and to be honest, if it doesn't get any use, it can be used as Anti K' fuel.
Comments are appreciated. I think the Foundation base can be tuned up a bit. Maybe fit in Glare from the abyss over something, possibly Manifest, since only a little over a fourth of the cards in the deck (and none of the attacks) can use it.
