I have never tried the HR rare card, but the slimes only need to be level 27.

For level 40 (R) you just need to use on of the arcanas (the light blue one with the wing) + level 27 slime.

For level 50 (HR/SR) you need to use both arcanas (the light blue one and the green one) + level 27 slime.

For level 60+, I either decide to use multiple level 27 slimes or just keep killing AW...
