You COULD get
Ent Draught in there without changing your deck too drastically. If you use
Pippin, In The Bloom Of Health, you can spot an Ent and thus get your Draughts out. That would require taking it to Expanded format, of course, but it's something to at least consider.
With an
Ent Draught and
Escape, Merry has 6 vitality, so he could still be up at 7 strength (9 with a sword) if you had all four
Everyone Knows out, even after exerting him twice for his ability.
Yes, combo-intensive, but once you have it all in place...wow.
