Spells becoming cast

[Nonex]

Both Food Chain and Endrek Sahr, Master Breeder are under my control. I announce Ulamog, the Infinite Gyre, and after calculating its cost, I exile Endrek with Food Chain to pay part of it. Has he lived long enough to see Ulamog being cast and generate 11 tokens?

[Nihil Credo]

601.2g. The player (http://www.yawgatog.com/resources/magic-rules/#player) pays the total cost (http://www.yawgatog.com/resources/magic-rules/#total_cost) in any order. Partial payments are not allowed. Unpayable costs (http://www.yawgatog.com/resources/magic-rules/#cost) can't be paid.

601.2h. Once the steps (http://www.yawgatog.com/resources/magic-rules/#step) described in 601.2a (http://www.yawgatog.com/resources/magic-rules/#R6012a)-g are completed, the spell (http://www.yawgatog.com/resources/magic-rules/#spell) becomes (http://www.yawgatog.com/resources/magic-rules/#becomes) cast (http://www.yawgatog.com/resources/magic-rules/#cast). Any abilities (http://www.yawgatog.com/resources/magic-rules/#ability) that trigger (http://www.yawgatog.com/resources/magic-rules/#trigger) when a spell (http://www.yawgatog.com/resources/magic-rules/#spell) is cast (http://www.yawgatog.com/resources/magic-rules/#cast) or put onto the stack (http://www.yawgatog.com/resources/magic-rules/#stack) trigger (http://www.yawgatog.com/resources/magic-rules/#trigger) at this time. If the spell (http://www.yawgatog.com/resources/magic-rules/#spell)'s controller (http://www.yawgatog.com/resources/magic-rules/#control_controller) had priority (http://www.yawgatog.com/resources/magic-rules/#priority) before casting it, he or she gets priority (http://www.yawgatog.com/resources/magic-rules/#priority).


So, no.
