Standard Compositions: Mechs
These different compositions are meant to display proven setups to strive for, for the very end game (top 4 and above). In general one of the seven slots will be the 'flex' spot, used to cycle new minions during the tavern rounds. Therefore, your actual board will rarely be as perfect as these listed here. Of course as many minions as possible should be tripled (the exception being minions with Divine Shield or Venomous) and buffed with Reborn, Venomous, Divine Shield or Taunt.
If you got a build that buffs multiple minions via Rock Rock, Nalaa the Redeemer, or Mrglin' Burglar, the ideal cards you should be looking for should have a special effect such as Cleave or Divine Shield. Alternatively look for unique effects like Impulsive Trickster or Wildfire Elemental. But in general, just buff any card. Don't roll for the ideal, it can cost you the game to desperately try to find them. You want to scale early, not later.
Also primary support units like Brann and Drakkari Enchanter will usually be tossed for the very last fights, but are sometimes displayed here when being integral to the setup. If one of your units is lacking, it is also often beneficial to replace it with a Leeroy the Reckless or a Transmuted Bramblewitch, before a deciding fight.
All available Mechs and Mech-associated minions
In general, Mechs have the upside of having numerous Divine Shield minions, the ability to resummon Mechs, and small token units. This gives them an advantage against venom/scam compositions and builds with low stats. Except for Beatboxer magnetization composition, this makes them weak against high stat builds like Demons, Elementals, and Naga.
Deflecto Reset Comp
When going for the Deflect-o-Bot mech strategy, the important aspect is to have your other mechs get destroyed so Deflect-o-Bot can regain its Divine Shield. This allows your Deflectos to deliver free hits without taking damage, a unique strategy that only Mechs and Quilboars have. The overall strength of your comp will improve by how much you will be able to buff your Deflect-o-Bots by utilizing magnetic minions, gems or similar means, during the tavern phase. Which units you pick for the resets is of secondary importance. Eventually you will want to transition into one of the following compositions.
Magnetization Beatboxer Comp
Buy as many magnetic minions as you can to profit of your Beatboxers and put it on any Mech you plan to keep until the end game. All of them are decent, so don't be picky. The spell Perfect Vision can buff magnetic minions in the Tavern.
Magnetization can be given even on full boards. Also, in the past it was possible to run out of Magnetize minions because the Scrapers pulled minions from the shared minion pool. But this was changed in a July 2023 update, now magnetized minions will return to the pool upon usage.
Shield Comp
The key with this comp is obviously to buy the cheapest spells you can. Land Lubber can help with that, but Lasso definitely makes it much easier. If you are missing any of these cards, Reaper, Beatboxer, Untameabull can all be good cards as long as you can apply Divine Shield on them. I would not recommend tripling any of these cards other than Charging Czarina.
Kaboom Comp
This build NEEDS you to have the Kaboom Bot Portrait trinket.
Ancestral Automaton Comp
Think of this build similarly to Eternal Summoner and Eternal Knights, except they get stronger for the amount of times they get summoned. So cards like Mecha Jaraxxus, Baltharak and Prosthetic Hand helps resummon them. Fortunately, the returning Kangor's Apprentice also resummons a board full with a combination of Titus. Leeroy can be any card, but preferably a card that isn't a Mech so Kangor's can't resummon it.
Trinkets that would go well with this include Automaton Portrait, Rivendare Portrait, Twin Sky Lanterns, Boom Controller, Mechagon Adapter, and Karazhan Chess Set.
