That's a ridiculously cheap regenerate ability, especially since the first ability makes it "free."

It only needs to say "whenever a creature regenerates," BTW.

Cheaper than free. Yow.

Eh, a one-mana legend needs something to make it interesting. That's a reasonable effect for a one-mana "regenerator lord" to have, I'd say.

Wasn't sure about the wording... never seen an effect quite like this before. After reviewing the rulings for regeneration, I see how it works now! Putting the shield on does not equal regenerating.

Yeah; but this is practically equivalent to "Every creature I control is invulnerable" as long as you have at least one land untapped.

I mean, it isn't quite - if they kill two creatures at once, you only get the mana back too late to save the second one; but very nearly.

Which... well, why would you NOT splash for four of this in any non-creatureless deck?

There's options... up the regen cost, add a tap requirement, change the trigger effect... for me the main gimmick is that regenerating causes something else to happen.

V: Regeneration is among the weaker ways to save a creature. Wrath of God or Incinerate effects bypass it, as do Last Gasp effects. First strikers don't get dealt combat damage in return. And, crucially, this doesn't give anything vigilance; the whole question of how much to leave back to block is just as relevant as before. (Nor, for that matter, does this help against evasion abilities.)

Sure, this is strong enough to be exciting, as legendary creatures should be. But I don't think it's too strong, and I certainly don't think it's unassailable.

So you just enchant this with Pariah, tap a basic land to regenerate it, then start repeatedly tapping a City of Brass that's enchanted with Fertile Ground and it's all good, right?

And now you need to change Fertile Ground into Overgrowth and have two other lands to make it start. Presumably you had those lands in order to cast Overgrowth to begin with.

ABH: Don't feel like you need to actually make any changes in regard to SM's comments :) He's pointing out a pleasing, silly, convoluted way to make an infinite combo with it... it doesn't actually mean there's a problem.

Noted... I do think a slight cost increase is warranted, anyway, as the cheapest repeatable targeted regenerate shield I can find is on Asceticism, which is . Everything else requires either tapping, sacrificing something, removing a counter, or a higher CMC.
