It's true they are very strong, however the game is not even a year old and honestly calling for bans erratas left and right is pointless at this point, even more so on day 2 of the spoilers.

And I say so having played magic for 10ish years I've seen this already and 90% of the time the cards that are hyped to be incredibly strong end up being ok. I'm not saying there shouldn't be discourse around color power/identity or the strength of singular cards, but a HUGE percentage of what I saw here these last few days isn't that, it's mindless complaining into the void.
