Mastering Gauntlets
I have plenty of reasons why gauntlets is a great choice to main. First, let us look at the characters who weld Gauntlets as their weapons. We have six character in total who weld gauntlets and they are Caspian, Cross, Kor, Mordex, Val and Wu Shang.
Caspian
I like Caspian particulary only because of his aggresive stats and the other weapon that he is welding, Katars. The Gauntlet and Katar is a great combination due to the fact that the player can go aggresive with gauntlets and afterwards use katars to finish their foes off. The only problem that i see new players doing is that they SPAM Caspian's Neutral Signature which thrusts out a charged bomb upwards and either to the top right or top left even if the enemy isn't above them.
Cross
Cross is very uncommon to see in ranked due to him becoming a meme as many new players like to spam with him. His stats allows him to be defensive and being great with attacking at the same time due to his defense and strength being relatively high with a decent speed. Cross is a very strange gauntlet legend who has strange signatures. His Down Signature, which summons a demon hand that moves towards the direction of where cross is facing over time, is a skilled move that has to be mastered if you are planning on maining him. You have to aim with the down signature in order to have the hit on your foe. The Blasters and Gauntlet is a very clean combination that allows the player to chip off damage with the gauntlets and end them with blasters or the opposite otherwise.
Kor
Kor is a very decent and skilled character and his stats allows him to be aggresive and durable throughout the match. His Down Signature is commonly done wrongly and results in spamming it. I wouldn't recommend using his signatures for gauntlets but you can use the gauntlets to unleash your fury and damage your foe. You can use your hammer to side air your foe or do the russian mafia earlier if you want to end your foe. I like the combination of this character as his hammer has got very useful signatures such as the Down Signature. I usually like to "sike" my opponent when im off the edge and gravity cancel and Down Signature which results in a very nice knockout.
Mordex
Oh lord, Scythe and Gauntlets. Much broken. Once you have mastered Mordex, your a god, alright. Mordex's stats makes their foes tremble in fear as he can attack on the run. Having a scythe paired with a gauntlet allows the player to go as aggresive as they can while chasing their foes. I mean he is a fury werewolf. I am not very experienced with him because i do not enjoy playing the scythe.
Val
Behold the "kill-bot", Val. The sword and gauntlet combo is amazing. Her sword side signature can go over the ledge and on the side of the ledge wall if you gravity cancel near to it. Her gauntlet side signature is spammy, which makes people salty when they encounter a Val. The proper way to play Val, is to try to not spam your signatures and use them wisely as you read dodges. Her stats allows her to go as aggresive as possible with gauntlets and defensive with her sword. I used to main her when i started the game and i spammed hell out of it. Don't fall into my trap brawlers.
Wu Shang
Particularly my favorite Gauntlet player. His signatures are very easy to land and you can slide charge over the edge with down signature if your opponents loves wall hugging. I main Wu Shang particularly due to the fact that i learnt a double fancy blackhole with signatures. His stats allows him to go half aggresive and half defensive. I like to do the "85 damage punish" (you will see it later).
Techniques
I would usually try to encounter players from the air by using down air or side air to waste their dodges and then i start the combos such as the gauntlet russian mafia. Try to keep repeating the combos until they realise that their are making mistakes and switch to another plan to oppose their actions. To oppose their actions, try to practice your spacing. Hop into training mode and warm up your buttery fingers by training your hand-eye coordination and spacing.
Dodge Reading
Try to watch your opponents dodges when you start your Side Light -> Neutral Air string and observe which direction they would usually dodge to several times until you are confident that they would dodge into that direction. Before a game, get into training mode and set the dodge reading on and try out all the dodges and try to dodge reads all of them. (if you can).
