Heroes Pool

In a match of Dota Underlords, players build their crew from a shared pool of heroes that consists of:
 * 30 copies of each hero
 * 20 copies of each hero
 * 18 copies of each hero
 * 12 copies of each hero
 * 10 copies of each

When a player sells heroes they are returned to the shared pool.

When a player is eliminated from the match, all heroes they have hired are returned to the shared pool.

In Duos, the size of the pool is doubled.

 * Increased number of each Tier 3 hero in the pool from 15 to 18.

April 30, 2020 Patch
 * Changed the number of units in each tier in the draft pool. There are now 30 of each Tier 1 unit (was 45), 20 Tier 2 (was 30), 15 Tier 3 (was 25), 12 Tier 4 (was 20), and 10 Tier 5 (remained the same). This should increase your odds of ranking up un-contested heroes, and in general encourage more diverse and unique crews in a match.
