For the pilgrimage to get your first legend card back, I sugest you some of this,
You need deck tracker
Beter focusing on winrate, so a lose streak wont lower you morale (much). If you get to rank 3 after just one more star to legend, check your winrate. If it still 60%, then you still good to go.
Recognize local metagame. To decide one deck to use for the climb.
Those two points can only be done with decktracker. So, use it.
Never swap deck, if the local meta are suddenly hostile for your deck, find beter hour to climbing.
Swap a tech card only when you get enough data from deck tracker.
Meager 56% winrate still need 200 match from rank 5 to legend. Thats why you need good WR decks.
Be focussed. Treat every star as your final star. Losing one star means, two more match just to break even (with 50% match)
Try to find your own missplay and error. Forget attacking with a token? Then you arent deserve the win. With this mentality, will reducing your tilt.
Tilting is dangerous. VERY DANGEROUS. Take a break when you lose. This will led you to hasty decision like deck/card swapping and more missplay.
Set a system to lower the tilt if you like. Example, everytime you lose, walk around the room, whistling with your mouth, or dont touch electronic for a full minute. This also lower the chance to rematching with your counter deck that just beat you. because in average, two player from a just finished match press the play button almost on the same time.
Try to listen slow paced song while climbing. Decision while having cool head usually better than the time you get agitated.
