Triple Triad Card drop idea

So I'm just gonna state this right off the bat I hate grinding for cards through npcs. My idea is why don't they make card drop rates for rare cards that are only available by one npc buffed just a bit(ie. Raubahn, Lightning), because lets face it 400 wins and no card drop is depressing just a slight buff to cards only obtained thru npcs please SE. Gauis is easily obtained through praetorium no need for his buff

At first I was happy they were bringing triple triad back, but the grind to get cards along with how shitty the tournaments are has made me want to quit altogether. I had to endure swift before his nerf but that also took over 200 wins. I hope these platinum packs actually offer these rare cards just so the whole grinding process is somewhat reduced, but if you troll us with another beastman or 2 star RIOT!!!

That's some shitty RNG

I'm in favor of a system where you can keep the drop rates as they are, but also add in an achievement as a buffer against having to win hundreds of games, like my 400-420 wins against Tataru T_T. For example, I can win Lightning card from Tataru with a 0.5% drop rate, or I can get it guaranteed after 200 wins against this NPC. If I am lucky, I win it on my 1st or 20th win, and then if I choose to, I can win the remainder and get a second from the achievement.
