The opening hand takes cards from the top of the equipped deck in deck order. After a card is played, it moves to the bottom and the next card fills that same hand slot. Normal matches therefore cycle the deck rather than randomly shuffling each draw.

Mana pays for Sidekicks and Spells. A played card returns to the bottom of the deck only after its placement or target is valid and its cost can be paid.

A winner also attempts to place the next crate from the saved crate sequence into their first empty crate station. Sequence position is persisted per player, wraps when exhausted, and is not a fresh random roll. No sequence crate is placed if every station is occupied.

Crates

Card crates grant one random card type plus Gold and Crystals. Gold and Crystal crates grant only their named currency.

Card Levels

Cards can reach level 10. The default upgrade formula increases unit health and damage, and spell duration where applicable, by 5% per level. Range, attack cooldown, movement speed, tile range, and mana cost stay at their base values under the default formula.
