If a replacement effect replaces a multi-event, it does not replace any of the individual events of that multi-event.

Example: Mordred Tide has the text “Until end of turn, if you would create one or more Runechant tokens, instead create that many plus 1,” which replaces the multi-event that creates X Runechant tokens with a multi-event that creates X+1 Runechant tokens. It does not then replace each of the X individual “create a Runechant token” event with “create 2 Runechant tokens.”
