WebbEDGs make nucleophiles stronger. With EDGs attached, a nucleophilic center is even more electron rich and ready to attack electrophilic sites. EDGs make carbon centers weaker electrophiles and less reactive to nucleophiles, because any (partial) positive charge it has will be minimized or nullified if the EDG is strong enough.
