It has been a challenge to gain collection power without buying cards specially now with the reward changes. Luckily, fighting brawls give a chance to buy gladius packs by collecting merits.
The gladius cards have the same card power as the untamed edition. Refer to this power chart from the pinned messages on the official splinterlands discord.
So if there's a chance, join a guild and fight brawls! But be sure to have the required building level to gain merits and buy packs. Another thing, there might be also sps rewards later on with brawls.
Here is my best pull on the gladius pack and it made me think that my luck is good with this set of cards because I don't even have the potions to increase the chances of legendary and gold foil.
