*sigh*

The real answer is how the games checks for Size. The game rules specifies that the Size Overflow rule comes into play if the total Size of the monsters is greater then the current limit when it checks it.

It checks this at every Rules Resolution. You can find these in the detailed rules.

Typically, in your query, this occurs BEFORE the attack fully resolves, so sorry but the attack fails as the attacking monster is gone. Of course, you can choose to keep the attacking monster on the field at the cost of sending the other monsters to the drop zone.

You're slightly wrong. The rule where you send the monsters on the field besides the one you callled, due to Size Overflow, only applies at the time when you call a monster. So, if 2 Stragrites are suddenly Size 3 at the same time, you can send either one to the drop zone.

As for the other part, It's not immidiate as is the games just has a lot of checks that occur. Typically at the end of when cards fully resolve their effects or at the end of a Counter Chain.

For example, INV Second Omni Demon Lord, Death Asmodai effect to call monsters actually allows you to call all of them, even if their total Size is greater then the field limit, as the Size Overflow rule only comes into play at the check, which applies when Asmodai's effect fully resolve, after it has called everything. And since all 3 monsters enter the field at the same time, you simply choose which ones to send to the drop zone.
