If Exploder Dragon attacks Thought Ruler Archfiend, does Thought Ruler gain LP?✓
Exploder and Thought Ruler are destroyed by battle.
Yes. Both trigger in Substep 7; turn player's effect is CL1, opponent's is CL2, and Thought Ruler's LP gain resolves.
Does Thought Ruler Archfiend negate effects of face-up Spells/Traps like Blaze Accelerator?!
A face-up continuous Spell/Trap activates its effect while Thought Ruler Archfiend is on the field.
No. Thought Ruler Archfiend only negates the activation of Spell/Trap Cards, not the effects of already face-up cards.
