Following jmg's example on Wreck // Salvage, it's not exactly a charm, but can we make a fuse split card with two "choose one" modes that all make sense together?

This isn't perfect, I'm not sure about the cost, and some of the effects want to be instant speed. And "deathtouch+trample" is complicated for many players. But "deathtouch + trample", "regenerate+trample", "deathtouch+fight", "regenerate+fight" are all combinations you might sometimes want.

I'd hoped to come up with something where you'd be more likely to want the individual modes, and feel clever when you occasionally got to use them together. But I didn't get further than "gains flying" and "N damage to target creature with flying" :)

Wow, awesome! Deathtouch+trample and deathtouch+fight are both very useful indeed, and regenerate+trample might be preferable sometimes. I was actually working towards a similar idea in parallel (with a "choose two" command-style charm), but this achieves pretty much precisely what I was after but better :)

One tricky thing about this is that, although any of the individual effects are only worth 1 mana, getting the combination of two is very strong. It's like you want to add a cost to the fuse. Might have to just upcost one or both sides instead though :/

The right side is strictly better than Pit Fight in two ways, so it should definitely cost at least . The left side should probably be at least , since it's better than Mending Touch (but obviously worse than Necrobite). Remember, each side of a split card should be a little overcosted so that the whole thing is fair.

Not strictly better because it's sorcery speed. That makes regenerate and fight and trample a lot worse. But I think your costs are probably right anyway, given that you're paying for the flexibility.

Yeah, the right side is closer to Prey Upon than Pit Fight. But for the extra flexibility in colour as well as in option, it should probably cost .

I missed that it was sorcery speed, since regenerate is much worse slow. Instant speed trample or deathtouch could cause pretty big blow-outs, though.
