Huh; only for this turn? I guess it can draw you a LOT of cards if you hit someone with a lot of scouts. But, um, if you can hit them with a lot of creatures they probbaly just lost the game anyway, so why bother?

Maybe its use is to make your scouts non-sneaky; so the opponent tries hard to block them and you can slip some damage in by a bigger creature?

It just feels limited. And costs a lot. So I'd make it a scout-lord creature, or enchantment; keep the ability; lose the 'UEOT'.

Oh; but that's clearly a rare or mythic, not an uncommon. Drat.

It's not like an uncommon like that is in a good spot either way - being limited to Scout tribal entirely. The spell probably should come with a general positive effect and then an added bonus to Scouts e. g.

> Whenever a creature you control deals combat damage to a player this turn, scry 1. If that creature was a Scout, instead draw a card, then you may put a land card from your hand onto the battlefield.

or

> Whenever a creature you control deals combat damage to a player this turn, draw a card. Whenever a Scout you control deals combat damage to a player this turn, you may play an additional land this turn.

Toned down further this could work as an uncommon lord creature, as Vitenka suggests.
