How To Play UFS: Attacking and Defending (Universal Fighting System)

I'm joined by Tyler today to show you guys the basics of attacking and defending!

What is the usual ratio of card types in a deck?

This game seems needlessly complicated

How often can I use my character's abilities ? Once per turn or once per attack ? I ask because the MHA Midorya states, Once Per Turn, is that how abilities on characters work all the time, or just on Midorya because the card states it ?

Hi guys! I asked a question on the ufsccg subreddit, but nobody there gave any kind of answer. Maybe you guys have the answer.

The scenario: I play Lightning, a 5 speed mid attack, for 2 damage. I open the enhance step with the attack's printed Stun: 2 ability. My friend then uses the effect of Warrior Descendant, a foundation card, and applies -4 damage to my attack. This would reduce my attack's damage below 0.

The point of contention: does the damage value of my attack continue to exhibit that negative value during the enhance step? Or, do any further bonuses to the damage value begin counting from 0 again?

My friend is of the mind that the remaining -2 damage reduction persists, thus requiring my enhance abilities to cancel it out before the damage value returns to a positive number again. I was under the impression that, because no attack can deal negative damage, that the reduction of damage from effects is capped at 0, and any left over penalties that would have put the attack's damage below 0 were no longer applied.

How is this supposed to work, and is there a point of reference for scenarios like this in the living game rules?
