Written into History -
Enchantment
Whenever a legendary permanent or planeswalker leaves the battlefield, you may exile ~ and return it to the battlefield as a copy of that legendary permanent or planeswalker except it is an enchantment in addition to its other card types.
Only the heroes and villains of war leave their footprint in history.

Hmm, come to think of it, don't think we even have enough legendaries and planeswalker to make this card work.

Reactive Barrier
Enchantment
Whenever a player casts a noncreature spell, put a barrier counter on ~, then counter that spell unless its controller pays for each barrier counter on ~.
"The more our faith is tested, the stronger it becomes."
