Uncommon lord for Rebels.

Partly due to aesthetics (having more than two of the same type of mechanic really bugs me), partly due to design space, I feel like this keyword would greatly benefit from being an action word, like fight or destroy. Consider the following wording:

"Whenever ~ attacks, uprise. Rebel creatures you control get +1/+0 and first strike until end of turn. (To uprise, produce at the beginning of your next main phase.)"

This could allow you to fit that flavor text in.

On most cards you can just use the reminder text like this:

"Whenever ~ attacks, uprise. (Produce at the beginning of your next main phase.)"

Using roughly the same amount of space.

Additionally, having it as an action word lets you use other triggers for it and - IMO most beneficially - tack it onto spells.

Idk man. An action word that is actually a delayed trigger sounds weeiiiird.

I'd restrict to "other Rebel creatures". Buffing itself makes it too strong at Uncommon.

How did you come to the conclusion that it's "too strong at Uncommon"? We've had cards like Splatter Thug, Thorned Moloch, and Porcelain Legionnaire at common.

I'm not entirely opposed to making the mana cost more color intensive for example (), but I don't really feel it's necessary. The rewards for going Rebels as far as tribal themes go aren't that numerous right now so I feel okay at this being quite pushed.
