Felixx I'd like to share my Zekrom stall, it's not so solid but indeed interesting and playable, here's the team:

tbh I didn't build this team around Zekrom at first but it did act better than I thought. Firstly I wanna build a team around defensive Lunala, which imo is a good wall due to it's access to shadow shield, my EVS set is to make it can roost to max HP even after tanking maximum special attack Kyogre-Primal's water spout and leftovers recovery, which can make u avoid risking the opposing Kyogre's Liquidation while switching in ur Blissey, otherwise makes the game very tough on facing with not only every set of Kyogre but also strong special attackers such as Geomancy Xerneas, Lunala's defog is to keep hazards away, since it can switch into some common hazard setters easily such as Necrozma-DM and Groudon-Primal (but be careful of the combo Rock Tomb then Eruption), anyway u can change it into Will-O-Wisp since it can check offensive Necrozma-DM more easily and avoid opposing SD Arceus take chance from it but Toxic is ok as well. Mega Sableye is a good partner of Lunala since it can bounce back hazards and can switch into many common hazard setters easily thanks to it's nice bulk, which can make Lunala is at full HP most of the time, besides it's a good check to some common physical attackers such as SD Ekiller and MMX. Ho-oh offers an answer to SR Arceus-Fairy, which is a huge threat to most mega Sableye stall teams, and it can tank hits, spread Toxic status or just defog with little cost, Sacred Fire is to deal as much damage as possible and whirlwind is to prevent set up sweepers take chance from it but in fact dd Zygarde with dtail can be very annoying, besides pdon is still a huge threat since only Lunala can deal damage on it, therefore I chose Arceus-Ground to check pdon and dd Zygarde, the main aim for using CM is avoid being shut down by Metronome Yveltal. Blissey is a common special wall that offers an answer to many special attackers such as Geo Xern and CM pogre, but as I said above u should not sent out it at first to pogre for liquidation can heavily damage it. Then I found that ground ceus is easily to be took down after several times of switch in, dd mega Salamence can deal a lot damage on it with a +1 boosted Double Edge then just sacrifice itself, after that it's hard to find opportunity for ground ceus to recover, this situation is similar on mega Sableye, it can't be 2HKOed by lo Marshadow but it can do nothing but to keep clicking recover, and so does ground ceus, therefore here's the physically defensive Zekrom, which is a solid physical wall that can tank 2 hits from physical Kyogre's any attack (including Ice Beam if it's an Adamant one), lo Marshadow's CC and even offensive Zygarde's Tectonic Rage or +2 Adamant mega Salamence's eq, which can let ground ceus don't be switched in too frequently. Draco Meteor is to punish dragon type physical attackers such as mega Salamence, Zygarde and Rayquazza and bolt strike is the strongest STAB that can deal a lot damage, which makes it not very reliable on Toxic to deal damage. That's all my introduction, be aware of opposing Zygarde and hope u can like this team. Sorry if I made any grammar mistake, English is not my first language.
