Wyand-level RNG, hell yeah.
My game against Calindu was like this.
G#1 (Grabbow vs. Grab DBH)
T1 his turn - Plays a QT gets an Entropy quanta. Turn goes, QT gives another Entropy quantum and a Gravity quantum. 1 Entropy quantum
gained from mark = 3 Entropy quanta for a next turn Discord.
my turn - Woohoo, 2 novas, 1 pend, Discords! = Next turn Discord! At least I thought so. Meanwhile played a Fog Shield.
T2 his turn - Plays Discord. Plays a QT gets another Gravity quantum. +Nova = 3 Gravity quanta, Black Hole. Entire game screwed.
I won't bother calculating the chances for this. Yeah, don't play hastily Nova when BH is possible, but really.
(Oh yeah, and no graboids - 5 copies - in the first half of deck... 35% Fog Shield letting through ALL Discord hits...)
G#2 (Grabbow vs. Dark Domin)
No Discord (3 copies) for the entire game (15 cards).
Despite the RNG it was an honor playing an Entropy Legend!
