Man, that's some insane luck, the average drop rate of golden legendary is about 0.003 with both potions. And having the other be a summoner, that's so good. I'm still holding my packs, because I heard there's going to be legendary summoners coming later from the airdrop. Airdrops will be available from packs once they've been revealed, so I'm waiting until the golden legendary summoners will be available from the packs.
