As the name implies, the two core cards of this deck are Thanos and Lockjaw. Ideally, you will want to play Lockjaw as soon as possible, then play an Infinity Stone on his location each turn to swap it for a higher-power card. Overall, you shouldn’t be too concerned with playing all six Infinity Stones to boost Thanos’s power, as this scenario very rarely happens.
Instead, you will seek to drop tons of high-power cards across the board while utilizing the utility of the Infinity Stones to swing the early game in your favor.
Leech, on the other hand, canremove the abilities of your opponent’s cards, allowing you tododge counters that the opponent may have, like Killmonger to destroy your Stones, Shang-Chi to destroy Thanos or Magneto, or Aero for disrupting your Lockjaw cycling. Overall, Leech is a great inclusion, and is especially good when summoned to the board through Lockjaw.
Substitutes
There are a few cards you may swap out of this deck, either for countering a popular card that you see frequently, or simply because you don’t have one of the cards listed above.
Magneto is one of the most flexible cards in this deck, and can be swapped for a few different options.Doctor Doomis a good choice that lets youcontest closed-off Locations with his Doom Bots, like Sanctum Sanctorum or Death’s Domain.
Although Doctor Doom takes up valuable board space, he can be great forcountering these locationsor applying equal pressure to all three Locations.
Another alternative for Magneto isKang. Kang the Conqueror can reallyfit into any deck, and provides the powerful ability tolook at your opponent’s turn before turning back time to the previous turn. This allows you tosee where your opponent is likely to play cards, anduse Aero to move themor contest different areas with Thanos or Devil Dinosaur.
If you’re finding yourself unable to play cards in the early game, try swapping out a higher-cost card like Magneto or Vision for something like Armor to protect your high-power cards, or Kitty Pryde for a consistent, low-cost card.
Playing The Deck
The general idea of the Thanos Lockjaw deck is toplay as many Infinity Stones as you canto draw all of your key cards, use Lockjaw to swap them out for higher-power cards, then invest into a second location to win the match.
Keep in mind thatLockjaw can only swap one card per turn, so playing a second card at his location on the same turn will not swap it. This can be useful on turn six, for instance, if you want to swap an Infinity Stone then play Devil Dinosaur or Aero on the same spot.
To gain the Power boost for Thanos from the Power Stone,the Infinity Stones only need to be played a single time. After that, if they are put back into your deck with Lockjaw, or destroyed by Killmonger or Elektra, the Power Stone will still count them as being played.The Power Stone is the only card that needs to remain on the boardto give Power to Thanos.
The Reality Stone is perfect fortrading out unfavorable locations. Typically, you will have a lot of cards in your hand because most of the Infinity Stones draw a card, so try tochange out locations that add cards to your hand like Lechuguilla or Orchis Forge.
Locations that prevent you from playing cards there or destroy your cards, likePlunder Castle, Death’s Domain, or Rickety Bridge, are also good targets for the Reality Stone.
Because of the amount of card draw you have with this deck,Devil Dinosauris an obvious inclusion thatalmost always has 13 or more Power, making it extremely cost-efficient. This card, along with Thanos, cancontest two separate lanes on their own.
There are a lot of different factors to consider each turn when playing your cards. Leech is one of your best counters against a number of cards that can ruin your game plan, like Killmonger, Aero, Wave, or Sandman.
Removing the abilities of these cards makes them effectively useless in the enemy’s hand, giving you a massive advantage. However, to compensate for this effect, Leech has a high cost and lower Power, meaning you’ll want tocheat Leech out with Lockjaw. Additionally, this abilityonly works on turn six, so you’ll still be vulnerable to these counters before then.
