You have Prince Imrahil the Fair but need support.
Look for Errand-Rider of Gondor or Birthday Escape.
Ways to draw after the normal draw. A draw-two reward does little if you spend all your mana on creatures and never draw another card.
You already have Prince Imrahil the Fair.
Consider Birthday Escape if it fills a useful job.
On your turn, the normal draw is card one. Birthday Escape draws card two, so Imrahil makes a Soldier; the Ring advances as well.
The support is missing
Take castable creatures and answers. If the engine never arrives, use the good cards rather than forcing narrow support.
