Name comes from ramdom card generator. Please comment, suggest changes, etc.

Welcome to Multiverse! Glad you've been having fun with my Generator too :D

This card is clearly similar to Jace Beleren. The cost and the -1 are identical. The +1 is very nice and the power level seems about right. It's stronger than Thassa, God of the Sea's triggered ability, but then it's only a Crystal Ball each turn.

The ultimate is pretty awesome, and looks like it can hit perhaps a bit too quickly given this is only 3 mana.

Overall, a very solid Planeswalker design. An excellent start to your time here on Multiverse :)

I made a few changes. See what you think.

I also changed the name--I started with my own name, then truncated it the way "Maro" was.

I think the power level came down a bit with your changes. Jace Beleren could draw you cards 2 turns out of 3. Now this guy only draws you cards 1 turn out of 3. I think [+1] / [-1] was a fine balance for the initial abilities.

The ultimate seems to have become rather worse. Not only does it only hit after 4 turns of keeping this guy alive, but it also only casts instants/sorceries now. I'd say make one or the other change: either make it -4 (well, maybe -5) with its current wording, or make it -6 but able to cast any nonland cards.

Fixed. Can someone verify the templating on that last ability?

Templating: If you're saying "nonland" then you can say "cast" rather than "play". The rest looks like it's all fine though.

...On the other hand, it's actually very similar to Chandra, Pyromaster's middle ability (just more cards and no need to pay the mana costs), so you can probably alternatively say "This turn, you may cast any nonland cards exiled this way without paying their mana costs."
