Leyline Waystone

Artifact

At the beginning of your upkeep, add . Mana does not empty from your mana pool as steps and phases end this turn.

I'd imagine that Nissa would keep one of these around, next make a mono-white card that gives them some in-theme but still strong card draw. For extra challenge, don't make it tied to creatures or enchantment being cast/entering.

Corin, Dragon Princess

Legendary Creature - Human Dragon Noble

Prevent all combat damage that would be dealt to ~.

At the beginning of your upkeep, if you control 6 or more creatures, transform ~.

2/1

Corin, Feral Dragon

Legendary Creature - Dragon

Lifelink, First Strike, Vigilance

At the beginning of your end step, if you control 3 or fewer creatures, transform ~ and put a +1/+1 counter on it.

4/4

Make another Fire Emblem themed card, if you don't like/play FE then any video game would do.
