Please, do something for Historic and Timeless.
These two formats are completely warped by a few decks.
Eldrazi in Historic is completely a mess.
Your decision to nerf a card for Alchemy, which also affected Historic, was completely pointless, since it affected a deck that was trying to compete against a deck that clearly plays another format.
You must return to cure the formats. They have been left to themselves for a very long time.
Please do something. Make MTG Great Again.
Keep nerfs and buffs separated for every format. A lot of cards in Historic should be sbanned (bolt, Blood moon - since Eldrazi exists, preordain - since ponder is stronger and already in the format. Uro, Oko, just to make some example).
Timeless needs more restriction.
I think you will understand all that with the real mess we will see this weekend with arena championship 10.
You should act. Do something. Mtg is getting worse day by day.
