By leveraging Sneak Attack to cheat a Dragon into play for just one mana, you instantly set off a dazzling chain reaction across your board. As that Dragon enters, Ganax, Astral Hunter and Lathliss, Dragon Queen spring into action alongside Cloudstone Curio, generating a valuable Treasure token and a 5/5 red Dragon token. When the new Dragon token arrives, Cloudstone Curio's triggered ability allows you to bounce your original nontoken Dragon back to your hand, ready to be redeployed through Sneak Attack once again. By sacrificing the Treasurers generated by Ganax, Astral Hunter to pay for Sneak Attack's activation cost, this loop becomes completely self-sustaining, letting you flood the board with infinite dragons and mana.
