Played my last game of the event after a bugfest and triggered another.

In Node C the added ability for ultimate is that when you trigger it, the next turn, if your opponent draws a card, you draw one instead and it gets full mana.

But the effect stuck and remained until the end of the match.
Whenever I was supposed to draw a card, Greg did instead, with full mana.
Greg was playing Jace2 that cast a support giving +4/+4 when he draws a card so he overwhelmed me pretty fast when he drew double and I couldn't answer.
