Hi Splinters, I have been thinking for a few days to spend my savings to purchase 22 Untamed Packs, which is cheaper than before. Still, after re-think and watching some people open untamed packs on Youtube, I decided to stop and not to "PUSH My LUCK" bet all my savings into Untamed Packs, which may not be "Gold Foil" cards or Legendary summoner. Instead purchase Packs, I decided to buy SPS and Stake it since the price is quite low, and I could gain some SPS Vouchers every day from staking them.
and hereafter, I purchase and stake SPS
With Vouchers I get every day, I will be able to purchase packs cheaper, and there is a chance of getting a limited promo card from Card Airdrop (if I correctly recall).
Note: Think again before making any decision
