If an effect allows you to put a card with particular characteristics onto the battlefield without instructing you to play or cast it, you consider only the characteristics of a modal double-faced card's front face to see if that card qualifies
you should pair this card with small creatures that enter the battlefield and draw cards or that have good abilities, like flying and double strike
