Let's be real here. There is no alt attacker for this deck that is any more than mediocre. Tropius is ok vs Suicune and you could make use of Return, but is that really what you want to be doing on T1? I think not. Bouffalant is also decent, but doesn't work especially well against non-EX Pokemon like Suicune. It's attack costs 3 Energy. Does it really make the deck that much better? Either Drifblim . . . eh, they're not bad, but they are Stage 1s, the Basic has a Retreat cost of 2. They help a bit against Plasma, but not much else. Virizion/Genesect has a very good set up Pokemon and a very good main attacker. It also has G Booster. The deck doesn't need something else to attack with that is almost always worse than Genesect, it needs to keep Energy on the Field for repeated G Booster/Megalo Cannon. That is why the loss of E Switch hurts the deck so badly. Fix that issue and you have a top tier deck.
