If you want to challenge other players in direct combat, you can take part in Tournaments. There are only five players in one Tournament. The top four players get Hero Cards + Silver as rewards. You need to beat your opponents one by one to win overall.

There is no participation fee! And you can win the following Hero Cards: Legendary, Rare, Uncommon, and Common for the winner; Rare, Uncommon and Common for the runner-up; Uncommon and Common for the third place; and Common for the fourth place.

Tournaments are divided by Tiers: they depend on players' Collection power. The higher Tier — the higher reward. Starting tier 11 winners also will get as a reward.
