Perhaps Wizards of Coast would consider in Free-to-Play - players could have competive Ranked play, by disabling use of meta-decks (relaying on Planewalkers/Artifact-cycling/Firebending/new bending builds/Life gain-loss etc) completely moving them in to separate section in whole as Meta-play or Pro-play tier or something like this.

It leaves, those tho would enjoy free-to-play in position to play versus overwhelming decks, which they have no chance to compete with.

Along with Planewalker's should have "Indestructibe" flag removed - some of them appear to be close to impossible to get off of table. Not be only "exiled" and deathtouch should work on them as on any other creature - damage done - dead.

For green for example there is no "exile target planeswalker" at all.

I just had black control deck with heavy removal playing vs. meta-artifact deck , which relies on Planewalker / artifact token creation - but with as it opponent has blue creature bounche/counter spell deck remains supressed in longterm - there is no way to remove all artifacts for black deck.

SO we back on square one - certain combos are way too overpowered for free-to-play "standart play" or "standart ranked" routine - u have to spend 4-5 years to get "metadeck" as free-to-play player, which in over 400 hours playtime is getting player frustrated and quit the game.
