Djeru, With Eyes Open
Oracle Text
Vigilance
When Djeru, With Eyes Open enters the battlefield, you may search your library for a planeswalker card, reveal it, put it into your hand, then shuffle your library.
If a source would deal damage to a planeswalker you control, prevent 1 of that damage.
Card Rulings
7/14/2017 If multiple sources would deal damage to one or more planeswalkers you control at once (for example, several attacking creatures), 1 damage from each of those sources to each of those planeswalkers is prevented.
Also, this is a good card that will make Gideon even more dominating. I can see the possibility of a strong white-heavy deck featuring this, both Gideons, and Avacyn. Yuck.
