Gilder Bairn

this, a paradise mantle, and a training grounds.
how many counters? would you say...(WOOSH) TEN MILLION?

Awesome. You can use all of the planeswalkers most powerful abilities the turn they come out with this card. Some other good combos are Helix Pinnacle and door of destinies.

3 mana for a 1/3 body is decent with a great ability. And this card has one of the best. Age counters, fading counters, sunburst, graft, Gilder Bairns will be a keystone in many deck builds. Get a set now and oogle at what is probably MTG's most inventive piece of artwork to date.

Planeswalkers yes... Helix Pinnacle no (It has shroud). Obviously designed for killing hatchlings, but quite the enabler in graft decks. Speaking of casual play, how about keeping that myojin indestructable ; putting the hurt on that darkest depths.
... and how friggin' cute is this guy by the way? Reminds me of the newer art for Blinking spirts, only I'm pretty sure he's laying out the glowworms, not collecting things.

Don't forget loyalty counters
