For Challenge # 075 and part of the Weatherlight Planeswalker Project. Ertai just really wants to counter spells, so I let him do it. +1 is Force Spike everything... though, it became simpler to word it as a tax, then to write out that spells would be countered if
wasn't payed. The second ability is a one turn Hesitation, which, while Ertai never casts that, was in Tempest, and seemed like the sort of thing to have Ertai flavor text... it just didn't. The Ultimate is a sort-of Meditate gone crazy; and while it doesn't counter spells itself, it's obviously going to be nutso good in a deck full of counters and, let's say 4x Urza's Rage. I should probably point out that, while I didn't intend it, Ertai on ultimate can double the mana in his pool if he responds to the upkeep trigger by tapping all his lands. Oh well.
I also made sure Ertai was kind of sickly as far as Planeswalker's go. His Legendary card is just a 1/1. I'm tempted to drop him to 2 loyalty counters to start... but that makes an annoying -2, neh?
