Unfortunately, there is no way around it. The point of the game is not to collect all available cards, but arguably create a powerful team to defeat all kinds of Archwitches.

There is no trading system in the game and summoning is just a big gamble. If you are unwilling to spend money, chances of getting SRs and URs solely depend on your luck from Archwitch drops or when Mynet feels generous enough to grant us a free UR card for a special ocassion.

There are cards that are available through Premium Summon, cards only available by amalgamating them, cards only available through ranking, and cards that are limited to certain events... and so much more. For that last type, however, unless Witch Gate brings them back, there would be no actual way of actually getting them.

What you can hope for, though, is for a future free card to have a Skill similar to the one you want. As a free player, chances of me getting bae Calamity are slim. Although the skill is weaker, the free Captain Saurva card sorta fills in that gap for me. With enough effort and time, even as a free player, you'll eventually be able to rank and get powerful cards.
