Splinterlands New Packs Chaos Legion - The Math to get guaranteed rewards!

Info provided by Splintelands Whitepaper:

1. Chaos Legion card packs will cost $4.00 USD each.
2. Players will need to spend a new VOUCHER token for each Chaos Legion presale pack they wish to purchase. 33,333.333 VOUCHER tokens will be created daily over the course of the 30 presale period (1M VOUCHER tokens in total) and will be awarded to all players who have SPS tokens staked in their in-game account based on the amount staked as a percentage of the total staked across all players in the game.
3. Accounts that have purchased 50 or more packs during the presale will be guaranteed to receive at least one limited-edition promo card for EACH 50 packs purchased, and accounts that purchase 1000 or more packs during the presale will be guaranteed to receive at least one gold foil limited-edition promo card for each 1000 packs purchased.

Math to get a guaranteed gold foil limited-edition promo card

1000 packs needed
Each pack requires 4$ + 1 Voucher
1 Voucher can and will be tradable/sellable, so we cannot say its price right now, so let's just get the math with the info we've got (Voucher AirDrop).
1M Voucher tokens will be airdropped. Let's suppose we will have 100 M SPS staked (Right now this number is 97M).

This means:

Please, note that there is a LOT of SPS that is LIQUID right now (not staked), that could be staked until the airdrop. That would require MORE SPS to get the same ammount of VOUCHERS as stated.

Considering 200M SPS Staked, the math would be:

So, we can say that we will need between 100k SPS and 200k SPS to get ONLY 1 golden foil legendary limited edition Card.

With the current price of SPS = $0,28, we will need between 28k USD and 56k USD only to buy SPS to get the Vouchers.

Now, with the packs price,we will need between 32k USD and 60k USD to get 1 golden legendary limited edition card.

For a MAX Golden, we would have to spend ~350k USD to 660k USD.

Please, take this with a grain of salt, like i said, Vouchers will be sellable, and this can change the WHOLE math.
Also, paying 32k USD to get 1 legie will also allow you to sell the SPS later on.
