3 Level 4 monsters
If a "Mathmech" card(s) you control would be destroyed by card effect, you can detach 1 material from this card instead. If this card is Xyz Summoned: You can detach up to 3 materials from it, then choose that many effects (you cannot choose the same effect twice, and you resolve them in the listed order, skipping any that were not chosen);
• Send 1 random card from your opponent's hand to the GY.
• Send 1 monster your opponent controls to the GY.
• Send 1 Spell/Trap your opponent controls to the GY.
You can only use this effect of "Primathmech Laplacian" once per turn.
