If you have your cards any sort of name at all, I would be much more inclined to comment on them.
Why in the world does this create a flying treefolk token?

Sorry That was supposed to be reach. I'm bad enough at names to begin with (I'm always open to suggestions.). I also tend to create a lot of cards. I am sorry that a lot of these don't have names. I'll try to work on naming things.

I don't mind you having lots of cards without names; it just means that in a recent changes list they're just numbers, and people aren't going to be so likely to click through to comment on them.

So this is basically a 3/5 reach with Suspend 5 - . 5 turns is quite a long time to wait; compare with Durkwood Baloth, Ivory Giant, and Phthisis for other things that made you wait 5 turns to get them - except they also had a mana cost so you didn't have to wait if you drew them late enough in the game.

I'd say this could either come down to 3 counters, or down to 4 and increase the token's size a bit. At that point you're running up against the largest size allowed for commons, but with such a time delay it's probably fine; and you want to encourage people to play this card at all.

Ooh. One alternative: make this also Wild Growth while it's on the land! So it's not just purely a waiting game, you're getting some benefit from this being on the battlefield rather than suspended in exile.

"Enchanted land gains 'Remove a counter from this land, : Add to your mana pool.'"?

I think that I will add a mana boost to the card. Also while this is kinda an alternate suspend there are a good amount of ways to untap lands so this could be rushed a little.
