Rule 420.4.b
Non-triggered abilities and conditional clauses that check cards being played do so by means of referencing whether said cards have been Finalized. Example: A player plays a spell, which is countered by Defy. Any Legion abilities of game objects controlled by that same player will be active. Example: A player plays a spell, which is countered by Defy. If that player plays Battering Ram and has played no other cards that turn, it will cost [4] Energy.

- If I play Singularity and my opponent counters it, can I still play Jhin, Meticulous Killer for [C] this turn?
- If my opponent plays two spells in succession, can I counter the first one with Crumbling Sands?
- I have a Ravenbloom Student on the board and I haven’t played any spells this turn. What happens when I play Rebuttal targeting my opponent’s Stupefy and pay [A] on resolution? After everything resolves, how much will Battering Ram cost? Will my opponent’s Legion abilities be active?
