You can equip Big Bang Shot to your opponent’s face-up monster, and use Spell Strider to banish your Big Bang Shot and 1 of your opponent’s face-up Spell card, to banish your opponent’s face-up monster that was equipped with Big Bang Shot, and potentially allow you to direct attack.
Any of these Crystal Beast monsters can be moved to your Spell/Trap zone as Continuous Spell Cards, when they were destroyed while in Monster Card Zone. You can use Spell Strider’s effect to banish your own Crystal Beast monsters from your Spell/Trap zone to banish your opponent’s face-up Spell cards.
Pretty efficient when dueling against a toon user. Made a couple of them rage quit out of surprise when I banished toon kingdom (they mostly had summon skull and toon dragon on the field) and my own spell card
UR's in general have a (low) level requirement, but they still show up if you're below it, just greyed out. (At least, this is how it worked before the Trader rework, I'd assume it's still the case.) It's in the active stock, so won't always be there. Just keep trying.
If you have played SSA, when you got 5* monster, ssa, and alo on the field. you practically begging the next draw is a monster. Any monster. More often than not, you will have multiple copies of alo and ssa on your hand.
This card is nothing compared to cosmic cyclone. Not to mention that you need your own face up spell card to activate it.
