Spd/Res Link Fodder?

So I have this Corrin with his Yato/eff and was wondering if it was a good idea to give him spd/res link to add to his support role while boosting his own. I was thinking of teaming him up with Laevateins def/atk link but is it practical with two swords even with all the visible buffs and combat buffs? The pic below shows his stats and setup. I'd like to give him DC when I can and maybe infantry pulse.
