Hello Splinterfans! Pogier here bringing the question, "Should I Buy Packs or Pool with the Megawhales for the Chaos Legion presale?"
I've been asked this question quite a lot and decided to sit down and write my thoughts on this. Let's discuss the benefits of each assuming you have a budget to buy 50 packs.
Buying Packs by Yourself
| Cost of a Pack | 4 USD |
|---|---|
| Guaranteed Promo Card | 1 regular card |
| Required Vouchers | 50 vouchers |
| Total Cost (x is price of voucher) | 50x + 40 USD |
| Discounted Cost if paid with SPS | 50x + 36 USD |
| Airdrop Points (300 per pack) | 1500 total points |
| Total Earnable SPS from airdrop | around 584 SPS |
| Value of SPS airdrop | 350 USD |
| Net Cost | 310 USD - 50x |
Estimated 251 days worth of airdrop
SPS is 0.6 USD at time of writing
with free 5 packs
Buying from the Megawhales
| Cost of a Pack | 3 USD |
|---|---|
| Guaranteed Promo Card | 1 regular card |
| Required Vouchers | 42 vouchers |
| Total Cost (x is price of voucher) | 42x + 30 USD |
| Discounted Cost if paid with SPS | Same as Total Cost |
| Airdrop Points (300 per pack) | 0 total points |
| Total Earnable SPS from airdrop | 0 |
| Value of SPS airdrop | 0 USD |
| Net Cost | 42x + 30 USD |
Based on the Airdrop alone, it is better to buy it yourself. You can even afford to buy the packs up to 5.56 USD and still have the airdrop pay for it (at no cost to you). Note that SPS is even poised to go beyond 1 USD in the future, so the value of the airdrop is even greater.
However, if you do plan to go with the whales, I recommend you go for someone with a plan for all the packs that will impact the game. If you're a fan, check out

Whatever you decide, I hope you consider all the points I brought up! Good luck to all of you!
