The deck does not use any legendary other than Bloodmage Thalnos which itself is more of a utility card rather than a late-game finisher. I have been playing control decks without legendaries and I find matches to be very long especially against other control decks with games constantly going into fatigue. Control decks usually use powerful late-game legendaries to end game and I feel having those will probably help to make games shorter.
