Question on "Torrential Pump" - Wellspring Ogerpon ex

The effect of the attack required to shuffle 3 energys, no "Up to" so why using the cristal, that only remove energy cost on teras, can skip the requirement of this effect? So for me it works like... You may shuffle 3 energys to use this effect, you don't have 3 energys? You can't use this effect... No matter how many energys the attack required, the effect is not completed when shuffling 2 energys into the deck submitted by /u/CookieAlfas [link] [comments]
