When spells are played at Abandoned Hall, if a Counterspell is played do you still get the +1 Might for playing it?

No, you do not receive the +1 Might from Abandoned Hall if the spell you played is countered.

According to Rule 425.1.b and multiple RiftJudge FAQs (such as #10646, #10825, and #8877), a spell that is countered is not considered to have been "played." Because the ability on Abandoned Hall requires a spell to have successfully completed its resolution process to be counted as "played," a countered spell fails to meet the trigger condition.

The sequence of events:

1. Initial State: You play a spell. This spell enters the chain.
2. Reaction: Your opponent plays a counterspell (e.g., Defy or Abandon) targeting your spell.
3. Chain Resolution: The counterspell resolves first (LIFO). It counters your original spell, which is then cleared from the chain.
4. Trigger Failure: Because your original spell was countered, it never finished the resolution process. Consequently, it is not considered "played" by the game rules, and the triggered ability on Abandoned Hall never enters the chain.

This interaction is consistent for all abilities that trigger when a spell is played; if the spell does not resolve, the trigger does not occur.
