So maybe everyone has already figured this powerful tool out but I thought I'd share it anyways. MagWave, or WaveMAG something like that. A Magwave is just mag wave dash back into something else, but there is a better way to do it, allowing for harsher follow ups. If you do a jump, mag, jump, airdodge diagonally back all with close timing, you will be able to get insane punishes including Upsmash even at high percents (Unless they DI mag correctly which no one does because it hits the opposite way from other moves making combo DI a nightmare)or another mag to continue a combo. Is useful, or am I just late to the party.
