I started a new account not too long ago, and formed the typical shrieker rush (short sword, 17 pillars, 6 graboid, 6 shrieker). Farmed AI3 continuously over the past couple weeks, short sessions of course, and slowly upgraded the whole deck.
That's great man, I love doing that myself. I mean yeah, it's boring, but it's not like you can't do other stuff while grinding
. Here's a few tips for future elements career:
1. AI3-Grinding doesn't lose value for high-level players. It' still the absolute fastest way to get score points in the game except for maybe Top-50 farming when there are lots of farms up.
2. On a related note, when you've upgraded your Shrieker-Rush deck, you might want to change the structure of your deck a little, because Long Swords are the absolute bananas. Atm I'm playing 3 Swords, 16 Towers, 6 Graboids and 5 Shriekers. It's like, of course you never want two of them, but when you have one, they're just insane.
3. I can't see a good reason to farm AI5 with an upgraded deck right now. If you want score, farm AI3, if you want money, farm FGs. AI5 can only be a nice hybrid solution if you're content with getting less of both, but still having a nice win%. If you're just aiming for max money/time, you should probably play Hope/Fractal, as that deck wins rather fast and knows very fast when it has lost. I know you'll need a few SoGs for that, but they can be acquired rather easily by T50-farming.
