I voted for:

Their Creatures have high costs, Gravity shield is useless and Thorn Caprice can ruin Otys Meal (unless it is momentumed)

Freeze quickly fades from Adredaline, Water Spirt is the only one with a useful ability (but dont get me wrong, rustler has a great ability but with 1/1 most people dont view it as a threat)

Procrastination shield is no problem, especially with adredaline, Lifes low cost creatures mean no problem for reverse time
