{3}{u}{u}: Until end of turn, Thopters you control
have base power and toughness X/X, where X is
the number of cards in your hand.

{2}{u},{t} : Draw a card, then discard a card. If the
discarded card was an artifact card, exile it from your
graveyard. If you do, create a token that's a copy of
it, except it's a 0/2 Thopter artifact creature with
flying in addition to its other types.
