Here's the first one:

"3 Level 4 "Meklord Army" Monsters
This card is unaffected by your opponent's trap cards. While this card is face-up on the field, you can add 1 "Meklord Army" monster from your Deck or Graveyard to your hand instead of conducting your normal draw on your Draw Phase. Once per turn, you can detatch 1 XYZ material from this card, select 1 card on both sides of the field. Destroy the selected card on your field and return the selected card on your opponent's side of the field to the owner's hand."

Second one:

CXYZ: Meklord Army General - Mekanikle
Rank 5
DARK
Machine/XYZ/Effect
ATK: 3000
DEF: 0

"4 Level 5 Machine-type Monsters

Once per turn, you can Special Summon 1 "Meklord Army" monster from your Hand or Graveyard in face-up attack position. It is destroyed at the End Phase. If this card has "Meklord Army Commander - Gigas" attached to it as material, this card gains the following effect:
- You can detatch 1 XYZ material from this card: All "Meklord Army" monsters you control gain 800 ATK until the End Phase. The turn you activate this effect, during battle between a "Meklord Army" monster and an opponent's defense position monster, inflict piercing damage to your opponent."
