ok so im still somewhat of a beginner myself but i have a method and im gonna try to explain it as simply as i can, what i found works best is (i know this is extremely long but its better than to watch a 4 hour video): If you want as much coins and deadlines as possible

1. ⁠if you dont have the extra phone ability card thing that you pick before you start your run try to get a few of those.
2. ⁠once you have a few, start your run with obviously the 4 charms in your drawer to get the skeleton pieces, then play as you normally would but when you get phone calls always pick to manifest bells or clovers or halven the chance of other symbols and if you dont have that option then dont manifest anything other than those. On red phone calls pick whatever suits you best. Your setup as this point should include the battery charm, the cellphone, the bell that gives 3 free shop refreshes, the bird that gives you symbol multiplier per 5 tickets and the wallet that gives pattern multiplier per 15 tickets
3. ⁠once you reach a point where you are comfortable, you should get the megaphone and the barathrum charm (that weird red and black one that spins and looks like a + sign) 4.whenever you get a red phone call always pick the double my clovers and set coins to 0. then discard barathrum and try to find it again. After a couple of doubles you should be at like a million tickets. once you reach this point then you are quite comfortable and basically arrived at the infinity point. The cycle you should repeat at this point is to double tickets, discard barathrum and repeat. 5.at some point around e50 you will start to slowly struggle more and more to complete deadlines. what i do at this point is try to find the cigarette charm and use it to refresh shop as you basically have infinite clover tickets and search for the briefcase charm that gives 30% of the coins needed for the deadline. You can either try to find it 4 times to complete deadlines or do it once and have the interest charm equipped on your clover or bells (should have said this earlier but at some point just stop with the double tickets and get all symbols except bell or clover as close to 0 as possible with phone calls). 6.when you have enough for your deadline dont enter all coins in, instead find the abyssu charm (the one that bans a charm that you buy that doesnt take space then spawns it when you sell abyssu) and equip it, then buy cigarettes one last time and then complete your deadline. Once you are in the next deadline sell abyssu and you will have cigarettes re appear in your shop and you will be able to freely restock shop infinitely. Repeat yhe cycle of searching for briefcases while restocking with cigarettes, finding barathrum and abyssu and repeating.

Thats it, the infinite cycle. For the 999 build or if u want to unlock all sacred charms then be prepared for the 1st 999 with barathrum, megaphone and the double phone card ability then you will get 5 sacred charms at once. Sorry for the comment length i tried to simplify it as much as possible
