If I play Confront, and then play Maduli the Gatekeeper, does he enter ready?

Ruling: Yes, Maduli the Gatekeeper will enter ready when Confront is active. His ability "I can't be readied" prevents the action of readying him (changing from exhausted to ready), but does not prevent him from entering the battlefield already in a ready state.

Sequence:

• Confront creates an effect causing units to enter ready
• Maduli is played from hand
• Maduli enters the battlefield in a ready state (not via the readying action)
• Maduli remains ready until exhausted
• Once exhausted, Maduli cannot be readied by any effect

Nuances:

• "I can't be readied" refers specifically to the action of readying (changing state from exhausted to ready)
• Effects that cause units to "enter ready" modify the entry state, they don't perform a readying action
• This same logic applies to other enter-ready effects like Bushwhack and Accelerate
• The distinction is between performing the readying action versus entering in a ready state
• "Can't beats can" still applies, but only to the specific action being restricted
