Unlock rules:

• Once Unlocked, the unit will appear in the furthest right slot of your shop on your next roll
• Unlocked units have the same amount of copies as other units of their tier. Note that units above 5 gold still count as Legendary (gold shop border) units and have the same unit pool sizes (9 for Legendary units).
• If multiple players Unlock the same Unlockable units they will be taking copies from the same shared Unlocked pool.
• If you Unlock a unit and do not have a copy of it on your board/bench, you will see it less often. If you continue to not purchase this unit and not have it on your board or bench, it will appear less and less down to a minimum of 20% of the normal appearance rate for that unit. This is to keep your shop focused on the units you want to field. If at a later point in the game you purchase this previously ignored unit from the shop, they return to the pool as normal.
• If you sell an Unlockable unit, it returns to that unit’s pool as normal
• For 4- and 5-cost Unlockables, if a small number of players have them Unlocked, the odds of them appearing after you have 3 copies become much worse based on the total copies in the pool. So if one player has a champ unlocked, buying 9 copies is much harder than a standard champion. This is to ensure three-starring them is roughly equivalent to three-starring a regular unit that can be contested. Note, once four players have that unit unlocked, their weight (frequency) returns to normal as they can be adequately contested.
