Special Summon this card from your GY (if it was there when the monster was sent) or hand (even if not), and if you do, its ATK becomes that monsters, but banish it when it leaves the field

C Common Link Bound X SPELL Quick-Play Target 1 Link Monster you control or in your GY
C Common Magical Merchant X LIGHT Level 1 [ InsectFlipEffect ] ATK 200 DEF 700 FLIP: Excavate cards from the top of your Deck until you excavate a Spell/Trap, then add that card to your hand, also send the remaining cards to the GY
The cherry on top of the cake is that it doesnt care if you have more lands already you still get to search
