Seriously, the "draw until you have 6 cards" skill is trash since it gives more advantage to you than your opponent.
It activates at the end of the turn, meaning you have cards in your hand that could have protected Osiris but you can't play them. Meanwhile, you also give your opponent draws that could give them the cards to deal with Osiris, even with the increased ATK.
the skill's awesome imo, i dont have to worry bout the amount of the cards in my hand when summoning slifer making it so i set my back row safely before the end of my turn to protect slifer then having 6k attack so things wont go over it. i can finally play my favorite God card withought stressing about it being weak or keeping cards in my hand.
