Does Runeterra have summoning sickness like Azuki’s cooldown?
NoNo. Legends of Runeterra has no summoning sickness: a unit played on your attack turn can attack right away. In the Azuki TCG every entity waits a turn unless it has Charge.
Cooldown in the Azuki TCG
An entity has cooldown the turn it enters the Garden: it can’t attack, and its tap abilities in the Garden wait too, unless the card says otherwise. That includes entities portaled in from your Alley. Charge lets it attack anyway. Cooldown never stops Defender, and leaders never have it.
Different
- Runeterra units can attack the round they’re played if you hold the attack token. Azuki entities need Charge.
- Runeterra limits attacks with the attack token instead. In the Azuki TCG you can attack on every one of your turns.
