­Grimgrin, Corpse-Born + ((C3266))

Huge non-untapping creature eating, zombie. Has 5's on it, +1 counters. And a 5-cost mana-making artifact.

This is just crying out for an Ashnod's Altar-alike.

Now, obviously needs some way to limit the abuse, but don't want to make a stompy creature you have to tap... let's make you need to attack or something.

Sadly, although it empowers sunburst; it can't feed off of it.

That's fascinating. Looks like one heck of an engine. I can't quite see the breaking combo off the top of my head, but adding 5 mana sounds like there's got to be one.

­Presence of Gond lets this tap for an insane amount of mana (5). 5 mana does seem like a bit too much; I'm sure this'd be worth keeping even at 3.

­Elemental Mastery goes somewhat insane on this. Infinite mana plus infinite hasty tokens. But then, I think that card does go infinite on Grimgrin, Corpse-Born as well...

To be fair, this creature auto-kills with a Hermetic Study, two other creatures and a Blaze. By the time you've made an infinite combo, you've probably tried too hard.

Well, the five mana was because of all the fives on the source cards; it's probably a lot saner at 3/3 for and . A cost on the ability would stop it going infinite; but yeah, wouldn't stop the "Ok, that's big enough, boom" effect.

I think you at least need a third creature; as it can't add mana from itself (no colours to select) I think. Maybe it doens't work that way and needs 'another' adding.

And I deliberately made it an artifact to make it easy to get rid of :)

I think it'd be saner as a 5/5 for 5 that (un)taps for 3.

Oh, wow, "its" colours? I didn't even notice that bit. I assume jmg misread it as well in the same way I did, "any combination of colours". Might do better to say "that creature's colours" to alleviate the misreading.

Yeah, I admit, I misread that. It's a cool thought, but this card has a lot going on with it, and the idea will probably be ignored by, then confuse people who play it.

I think most of my and Alex's comments have more to do with the brokenness of than any real balancing issue. If you really wanted to make the activation hard, you'd add another 5 in there, and ask for ~ to sacrifice 5 permanents. But who wants that?

I just wish there was a way to stop this guy before he went nuts. Something like 'When this creature is targeted by a spell or ability, it gains summoning sickness until end of turn'. You obviously can't add that line of text without getting screams of anguish... but, on some combo creatures, the idea of it would be nice.
