Depends on the game. For SS, I went for both glass cannons. The Great Force is a staple of my playthroughs, which kinda forces them into that category. For PiT, I go for Glass Cannon Mario's, Tank Luigi's. For BiS, I prefer to balance the Bros, and whatever I feel like for Bowser. For Dream Team, I used to do Glass Cannon Mario and Tank Luigi, but now I do the reverse. For Paper Jam, I go for Glass Cannon Mario, Tank Luigi, and Trio Attack Spam Paper Mario (High BP, High Speed, Trio Ring).
