It’s Ash’s Pikachu versus Sawyer’s Aegislash in the semifinals of the Kalos League! Sawyer presents a strategic challenge when Aegislash leaves the battlefield covered with fallen trees, but Ash and Pikachu figure out how to use that to their advantage, and Aegislash is defeated.
Then, something unusual happens: a double draw, as Ash’s Noivern and Sawyer’s Salamence knock each other out, and then it happens again with Ash’s Goodra and Sawyer’s Slurpuff! Sawyer’s Sceptile defeats Pikachu—and finally, Ash-Greninja and Mega Sceptile face off in an amazing battle of rivals. The battle is fast and fierce…until Ash-Greninja emerges victorious, and Ash moves on to face Alain in the finals!
