Infinity of the Sacred Beasts - Raviel, Lord of Phantasms X DARK Level 10 [ Fiend / Effect ] ATK 4000 DEF 4000 Cannot be Normal Summoned/Set
Discard one card, draw three cards
Furthermore, I noticed this mistake in the text, the second effect doesn't say "can" after the : so its a mandatory effect, so you might want to change that
With time, as new mechanics are introduced in this format, a lot has changed
Cards can look very similar, be of equal rarity, and yet be of drastically different value based on external factors like popularity, taste, and even just hype
Not only that, its 8-Star Level means it only needs two tributes for a successful Summon, making its resource requirements just the same as the likes of Dark Magician and Blue-Eyes White Dragon but with better offensive power.
