To butt in, this actually a lot more straightforward than Invoker's casting system. When the latter uses Invoke, he "creates" a spell and places it in a queue of two spells, both of which require extra buttons to cast. Invoking a new spell puts it in front and pushes the queue back, deleting the oldest spell. Oberon's casting mechanic makes him a little more reliant on memory, but allows him to cast spells a lot quicker.
