"I'm kind of bored, let's switch to another game."
When Ash faced his tenth consecutive defeat of the night in "Mage Duel 14," he suggested what Diya had expected.
Tonight, Ash abandoned the wandering Sword Saint he had been cultivating and employed popular characters like the Alchemist Dominator and Earth Empress. He even used special characters such as the enemy Mage and the Sorrowful Green Scythe, all of whom shared one feature—they had simple and handy loop suppression routines.
In short, they were 'Spear Moves'—a term from the "Mage Duel" series, referring to tactics as simple and practical as a spear thrust that are difficult to counter and great influence on the game's enjoyability, which is why players would agree to disable them by default.
Don't assume that only Ash had read the "Complete Mage Duel Series Strategy Guide"; Diya also made time for Liss to read it, naturally, they both knew about these Spear Moves.
