So this is interesting. It's KINDA evoking "Counter target spell that targets one of your creatures", the cost being the hint to counterspell. But it's really actually whiter-style denial. And you have to make the choice at the start of your turn; which is interesting but, like oh so much of fallen empirs, weak.

Although I did like merfolk tribal in FE; this card neevr saw my deck, I preferred the force-spike wizards.

So how does mtg currently do such "Protect your other creatures" cards? Hexproof instead of shroud is a no-brainer. Which removes some of the tension from having to use this at start of turn; which is a shame.

The closest I can find in theme to this is Dive Down. But I really don't want that on a stick!

I think it would be better to make this a more permanent partnering. Sure, why not; move as a sorcery should work.

as partner is a thing nowadays, could you use soulbond from Innistrad instead?
