Triage analysis

Clarified summary

Endless One cannot be cast with a nonzero chosen value for X even when the player has sufficient mana.

Oracle text

Endless One has mana cost {X} and “This creature enters with X +1/+1 counters on it.”

Investigation findings

The authoritative parse marks the enters-with-counters replacement supported and explicitly derives its counter count from CostXPaid. The screenshot provides concrete reproduction evidence; the failure is in choosing/paying X during casting or its UI round trip. No exact duplicate was found.

Acceptance criteria

• Casting Endless One prompts for a legal X value.
• The total cost correctly includes the chosen X and can be paid from available mana.
• On resolution, Endless One enters with exactly X +1/+1 counters.
• X=0 remains a legal choice.

Classifier analysis

Verdict: supported_aspect_defect
Matched clause: Enters with X +1/+1 counters, represented by CostXPaid (supported: true)
Reasoning: Card data claims the X-dependent behavior is supported; the report shows the casting/payment path cannot supply the value that supported replacement consumes.
