Tremayne said: @Mburn7 - very true. These cards will not create any loop (I tried to make a couple of looping cards but they just felt samey to BSZ, so I thought up something different).The red and green can instantly kill most PWs with a few support cards, but they should kill in two rounds and perhaps prevent being killed by a BSZ loop.I agree the black one is not very good. I had an idea about discarding cards and then either apply some kind of effect for each type of card discarded this way or return a number of creatures from the GY, but creatures just felt like the green card was copied and I couldn’t find any effects that was really thematic.so this was I came up with during writing the post.
Mburn7 said: I would think an OP-level black card would be something like a plague wind that also reanimates a bunch of stuff (at least 3 creatures should do it). But even that isn't nearly as strong as BSZ. I don't think anything even can be (since even HUF is a bit tricky to cast sometimes and has a small downside)
