Otes being the Dio Brando of the Rush anime is the funniest result

Is lightning vortex, a strong card that will see play in the format? yes, but the format has enough answers for it not be broken/format defining

Though it is important to note that Ryozai got limited on the most recent banlist

Not really
1) Dark Hole is already in the format as a legend and that card generally now only sees play in side decks

2) these are two of the most popular staples in Rush now

It ain’t the best but it is what it is
