Can somebody pls explain how this card exactly works?
Lets say if the enemy has 2 trap/spell cards facedown and plays riryoku e.g. from his hand, can i use straight flush in that situation? and if so, i assume that the cards are destroyed but the effect of riryoku is not negated?
and can it be used in every phase of your and enemies turn?
This is the perfect example on how a card created for a 5 cards game can become insanely strong without any reasonable purpose.
This card could be classified as "NORMAL"-rarity (and thus easy to get in multiple copies) if its activation condition were hard to be hit; this would have been true for a 5 spellcards field, hard to be filled. On the opposite hand, in duel links filling the spell/trap zone is quite a common happening, making this card a nightmare for every player who relies on spell/traps...
I don't think I like this, as much as I don't like the decision of not putting any limitation on many cards such has kuribos or controllers, but hopefully someday things will be fixed and balanced for the players' sake.
