So I kinda like the card Splinter twin from ROE. The problem is that its doesn't really go in any decks that are good for standard. There are some fun looking combos out there, but I'm looking for something better, more useful. Then it hit me Splinter Twin + Allies! I think that ST fixes many of the problems with the current ally builds. It allows you to play allies at instant speed, its is a continuous source of allies, and it is as versatile as your deck because you can put it on any of your creatures.
Imaging putting ST on an Evangel, all your creature get bigger, and prot from two different colors. I think that with proper play testing ST could fill the spot of Join the Ranks, and be pretty kick-ass.
Let me know what you think.
