Red Frog:
The Suwakos aim at your position. When the card starts, misdirect her straight down, then go right. She should now aim mostly horizontally, just slowly move up (tap up when you hear the shooting sound, you don't have to move otherwise). When you reach the top, make sure she is to the right of you, then go to the left side of the screen. Let her shoot twice, then start slowly moving down. The 2nd Suwako should appear around this time and, if you did it right, will also be aiming horizontal only. Repeat the circle, only be quicker when switching back to the right side than you were switching to the left at the top. Just make sure neither Suwako is above or below you when they shoot.
