Some of you might not know what this move does because it is never used competitively:
For 5 turns, all held items have no effect.
Don't build a team around it, just have one setter of it on your team to deal with certain pokemon and make sure your team doesn't suffer too badly under Magic room. Magic room is like a double edged sword in the sense that your items don't work either. However, embargo will always be gimmicky. Yes I know that pokemon can still mega evolve under the effects of Magic room. First of all, let's go over some pokemon that are easier to deal with under the effects of Magic room.
-Gliscor
-Resto-chesto Rotom-W
-Smeargle
-Alakazam
-Most walls
-Anything with the Unburden ability
-Acrobatics users
-Eviolite users
-Scarfers
Let's go over the list. Gliscor can't activate it's Toxic orb under magic room meaning that it has no way of recovery (roost is very uncommon). It is also very common so it makes Magic room slightly less situational. Resto-chesto Rotom-w is literally the most used pokemon at the moment. Try and use Magic room and make that low health Rotom just suicide itself(This works for other resto-chesto users as well but Rotom-w is the most common). Smeargle relies heavily on it's Focus sash because it can't take a hit otherwise and there are a lot of pokemon outspeed it and OHKO it. Alakazam is a lot easier to deal with if it's sash is broken and if it is a mega set then you can still OHKO it quite easily >.>. Most walls rely on their leftovers recovery and don't have any reliable way of healing. Pokemon with the Unburden ability (Hawlucha sems to be common at the moment) need the item to activate their ability and, since they never run speed boosting natures, they are slightly easier to kill. Acrobatics users are really hindered in Magic room (Before they use up their item) as their strongest STAB is halved in power. The most used example is Talonflame and I guess Hawlucha but that isn't too common. Eviolite users suffer greatly as their defenses are only average without their item. Chansey is the most common Eviolite user and it can't take physical hits without it's beloved item (It can still tank special hits quite well). Other less common Eviolite users suffer a lot more. Some scarfers are a lot easier to deal with under the effects of Magic room (Especially Genesect).
Now let's look at some Magic room setters:
Banette
Item: Banettite
EVs:252hp/252atk
Ability: Frisk
Adamant nature
Move 1:Taunt
Move 2:Magic room
Move 3:Phantom force
Move 4:Pain split
Banette is probalby the best user of this move because of both of it's ability Frisk, it can still use it's item under Magic room and it's ability Prankster after mega evolution. it also get's Taunt which is nice. I don't want to go into too much detail about these sets but those are the reasons why Banette is a good user of Magic room.
Klefki
Item: Leftovers
EVs: 252hp/252spdef
Calm nature
Ability: Prankster
Move 1:Magic room
Move 2:Spikes
Move 3:Thunder Wave
Move 4:Foul play/Dazzling gleam/Flash cannon
Klefki is a good choice because it is already a good supporter and has the ability Prankster. Also, like Gardevoir, it usually has a free moveslot and Swagger still sucks.
Gardevoir
Item: Gardevoirite
EVs:252spatk/252spe
Ability: Trace
Timid/Modest nature
Move 1:Magic room
Move 2:Hyper voice
Move 3:Psychic/Psyshock
Move 4:Taunt/Will-o-wisp/Focus blast
Gardevoir is a decent option. Mega Gardevoir usually has a free moveslot open so why not give it Magic room? That's pretty much all this set it. It's an offensive Magic room setter.
If Magic room is active, try not to use pokemon that rely on their items too much. Most things are just fine to use under Magic room but these pokemon are good to use:
-Mega pokemon are completely unaffected
-Choiced pokemon have some time to choose their move before locking themselves into something.
Leave your thoughts on Magic room here. Like I said, don't build a team around it and only use it when appropriate. Only have one setter per team and, while it does have some uses, it's not completely game-changing. Still it doesn't suck and helps deal with some common pokemon.
