Since it only reduces your opponent monster's attack, your defensive choices should be ones that don't switch them to defense. Since its effect almost ensures that you can go over their attack, Super Rush Headlong works well if your attacks are negated and have to defend for a turn. Wall of Disruption and/or Mirror Wall can also be very useful for defensive uses.
Gigaplant’s effect can be a good combo good combo to Special Summon this card from your hand or Graveyard as you can half the ATK of 1 of your opponent’s face-up monster, giving you a chance to OTK your opponent .
....who runs riryoku, dont worry ill wait. also situational if you dont draw both you lose if your deck is SOMEWHAT NEAR CENTERED ON THAT AS A WINCONDITION. this can be abusable in burn use be to run over your opp monster halving it and then dealing residual damage as well.
I remember this card from 5ds manga, Yusei vs Sect
