A "Spell" Spellcaster

Look I get we have a lot of mages, even Ryze is a spell caster with a book. But I want a combination type of spell caster. Ya know, someone who reads out spells from a book, per se. And maybe, just maybe, each button (QWER) is a different word so that when you use them in certain orders OR in combination with other spells, it does something different. Like think Q is the word "Force" and W is "Protect". A standalone Q is force palm skillshot. A standalone W is a shield. A Q and W combo could transform the casted spell to become an AoE knockback with a shield. I feel like such a high skill champion could be fun because the playstyles would be different for each game as this champ. Just a thought since we technically just have casting mages that don't require any text reading. And, of course, put in your own thoughts, ideas, and comments.
