Lets say we are on level 1. When Redcloak is placed into battle.

Redcloak is a Leader (Battle size +1) and when supported by Goblin's has the Horde (Battle size +1 per supporting card). So, if we start with Redcloak and the additional monster I play is a Goblin, would that further expand the battle size to 3?
Correct. And if the 3rd card is a Goblin, the battle sizegrows once more. And recall that supporting cards are everything on the same floor that supports, not just what's in the room.
