Mashup of Farhaven elf + Toiling Tiller.

I originally envisaged a giant creature that landsearched, but everyone is tired of Primeval Titan by now. This seems an obvious alternative. I'm not sure how strong it is: early game you'll rarely use the regeneration, and it costs 2 not 1. But it's potentially very powerful to turn your acceleration into an eternal chump blocker when you don't need it any more.

I like that. Interestingly, of course, if it's untapped it'll only actually cost to regenerate. But it's turning a fair bit better than just turning into a chump.

I like it too. You're giving up a bit to get a 2-drop accelerate rather than a 1-drop, so it probably won't be any good in Constructed if Llanowar Elves/Elvish Mystic are in Standard, but in Limited or formats that don't have the 1-drop alternative this is great. Early game it's an accelerant, late game it's a regenerating blocker for big things. Very solid.

Thanks!

I was thinking of Sylvan Caryatid as another 2-mana mana-acceleration with a defensive body, but I forgot that was any colour. I normally want my acceleration to ramp out large green monsters, I forget it's more powerful to play the most powerful spells of any colour :) This could certainly be pushed further, but doesn't need to be.
