8/24/2016 - The idea of reverse ninjutsu has a lot of promise, but executing on it proves dangerously unwieldy. Here are three, and I'm not sure any of them make the cut, but one at least comes close.
Ruse reverses ninjitsu by making you worry about blocked creatures, rather than unblocked ones. It nudges you away from blocking instead of toward it, acting more as evasion for your attacking creatures than a saboteur effect.
Bait reverses which of your creatures the mechanic goes on, the apparent attacker or the villain lying in wait. Being able to bring any creature in opens your options up quite wide, but letting your opponent know where to expect trouble reduces the surprise; Bait becomes an evasion ability. It's a daunting one because it uses the unknown as a threat, and the unknown can be very threatening, but it's also dependent on keeping a creature in hand or bluffing that you have. So it's dynamic evasion, a bit like prowess, and that's cool.
Unfortunately, it's also problematic to execute. We either abstract what's happening (as above) or write it all out (on the right). When the short way is six lines, you're looking at a terribly expensive keyword in terms of rules box space and NWO complexity. Ruse isn't much shorter, but every bit counts. For that reason (and for developmental concerns with the more open-ended version), I'd push ruse over bait.
Aaand I accidentally made a bunch:
Let's see your ruse (or bait) designs (or fixes).
