I would start here to get a idea and plug your specific champions into the calculator.

ye im already on that, but its not that easy anyways. i cant find a working speeds with mashalled. I have lydia but id rather not regear her :<

Have you tried comparing it with the heiress version speeds? Both comps will have the 30% speed buff taken into account. 

Would you consider swapping Cardiel for Hieress?  If so, this tune works with Demytha, MaShalled and Seeker, along with Hieress and a DPS

It's a 3:1 tune for everyone except the DPS, which is 2:1.  Some of the speeds are quite high though depending on where you are at in the game

Unfortunately you cannot just swap Hieress for Cardiel 1:1 as you lose the increase speed buff, but it might be an easier comp to build in the meantime as Hieress is a cheap champ to get

Thats probably what I was looking for :D thanks. I just have to adjust speeds because of cardiels aura. but it should work

Ok I tried it and it didnt work. Turns out that heiress is a key champ. Her speed buff overlays the ones from mashalled which is kinda weird since he can reapply it every 2 turns :O 

I can sub her with lydia but still thats not the point im trying to make. 

If you have the champs just do the demytha+heiress comp and use your mashalled as a dps.

Yea, it won't be a straight swap unfortunately.  The increased speed boost from Hieress is part of how this is structured

heiress is there not only for the speed boost but to go after each turn of cb to cleanse debuffs.

True, but so does Cardiel.  Both are on a 3 turn cooldown too, so he could replace her on that front with the same speeds.  It's the increase speed that he doesn't bring
