Pin this for any one thinking of keeping their XF and building the TOTY from scratch

NOTE: DO NOT take this as an endorsement to buy an XF and upgrade them now
This is for those who've have the XFs all along and only need 2-3 tiers to get them to 92ova

Here's a little math for y'all:

To take the 92ova XFs to 99ova, you'll need 54x PUCs
Those 54x PUCs will take 2160 79ova or less Gold players to make

Those same 2160 Gold players can make 61x TOTY Collectables
(and you'll have 25 gold players to spare).

Meaning, it's cheaper to trade in the XF now and get the TOTY
vs skipping the event and keeping the XF or keeping the XF and building from scratch

Just upgrade the XF and trade it in
