Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Variance · Grand Arena
Turn-based fantasy football where orcs, elves, and dice decide the league.

Variance · Grand Arena
A digital card game balancing opponent reads against draw variance.
Blood Bowl 2 leans Variance (Grand Arena); Hearthstone leans Variance (Grand Arena).
Hearthstone leans a little harder on execution, though the gap is small.
Blood Bowl 2
Turn-based tactics; no reflex demand
Hearthstone
Clicks only, no mechanical skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blood Bowl 2
PvP positioning baits opponents into bad dice commitments
Hearthstone
Human opponents bluff and adapt mid-match
Blood Bowl 2 leans a little harder on variance, though the gap is small.
Blood Bowl 2
Block dice and failed pickups decide entire matches
Hearthstone
Draw RNG and discover effects swing games
Blood Bowl 2 leans a little harder on optimization, though the gap is small.
Blood Bowl 2
Risk-ordering actions and team development are deep solvable craft
Hearthstone
Deckbuilding, mulligans, and mana curves matter
