A champion idea

1. My idea would be about for different champ swapping with R. Like u press R and ur spells become 3 switch possibility. 1 would have attack speed and crit, one would have dmg and life steal, one would have more range and lethalty and one more tanky.

2. The rescource bar would be filled as u fight with all of them to use the ult with R (only when full)

3. They would be able to be played pretty much all role, top, mid, support, jungler and maybe adc if you use melee champ adc. they could be figther, assassin, tank etc

4. As a theme you could use an element or something.

P.S. I just found about the twin yordles so I dont think you will be able to create it. But still just wanted to give an idea of an all role champion.

Comments if you like the idea or not it helps.
