Looking up the Sacred Beasts, it might be even worse because It doesn't even have to be a trap, Uriel just straight up nukes a face down for free and you can't activate other spells or traps in response.
ha
Hamon will also be a pain in the ass because it forces you to attack it if it's in defense and reduces damage to 0 on the turn that it's destroyed. And it has 4k defense and only requires three spells being sacrificed for it.
Not to mention even if Marik did get a high atk Ra on the field, Raviel can boost itself by sacrificing the others (or the tokens his effect summons) to match or better ra.
Yeah I might have given Marik too much credit on the grounds of anime Ra being powerful. This is a pretty bad match-up for him.
You would need all three Egyptian Gods to hard counter the Sacred Beasts, I don't think any one of them would beat them alone.
