Mastemon (Alternate Art) (ST10-06) [Digital Hazard]

[When Digivolving] Place 1 yellow or purple Digimon card from your trash on top of your security stack face down. When DNA digivolving, you may search your security stack for 1 level 5 or lower Digimon card and play it without paying its memory cost. Then, shuffle your security stack. [All Turns] When you play another Digimon using an effect, delete 1 of your opponent's Digimon whose level is less than or equal to the played Digimon's level.
