+2: Reveal the top card of target player's library. If a creature was revealed this way tap all creatures with the same name. They don't untap during their controller's next untap step. Deal 2 damage to each creature tapped this way.
-4: Deal 4 damage to each tapped creature.
-10: Take an extra turn after this one. During that turn whenever you would draw a card you may draw an additional card.
See Challenge # 129.
Okay, it feels taboo to do my own challenge, but science team.
The -4 ability is my favorite off of this. I think I really combined Tamiyo's tapping abilities with Ral's damage.
The +2 seemed like a cool idea when I thought of it. I still like the concept, but it seems awfully wordy for a planeswalkers first ability. I honestly think this would be better as a UR instant. This ability also has the problem of having a high chance not to do anything. In the original design it was look at the top 5 cards, which is probably too good. Maybe top 2 might be okay.
The ultimate was kind of thrown together after looking at Tamiyo's and Ral's ultimates.
