1 tuner +1 or more non-tuner "Spider" Monsters.

When this card is succesfully Synchro Summoned place 3 "Web" Counters on 3 face-up Monsters on the field. Monsters with web Counters on them cannot change their battle position, except due to an efffect. Whenever your opponent's Monster(s) attacks it is changed to defense position and it's DEF becomes 0 until their next standby phase. During battle between this attacking card and a Defense Position monster whose DEF is lower than the ATK of this card, inflict the difference as Battle Damage to your opponent.

This card cannot be Normal Summoned or Set. This card can only be Special Summoned if you control less monsters than your opponent. When this card is Summoned, you can search your Deck for an Equip Spell card and add it to your hand. This card returns to its owner's hand during the End Phase of the turn it is Special Summoned. When this card is sent from the field to the Graveyard, monsters you control with Equip Spell cards cannot be destroyed until your next standby phase.

1 tuner + two or more non-tuner water monsters.

Once per turn you can change the battle position of a Monster on the field. It cannot change it's battle position and cannot attack as long as this card is face-up on the field. When this card attacks, it gains ATK points equal to the number of water monsters on your side of the field x200.

1 tuner + 1 or more non-tuner Beast-type Monsters.

As long as this card is face-up on the field, beast, Beast-Warrior, and Winged-Beast type Monsters you control cannot be destroyed by effects They also gain 600 ATK points and can attack twice in the same battlephase, but their second attack cannot be a direct attack. When this card is destroyed and sent to the graveyard you can Special Summon "Eva, the Essence of Feral Beings".

(dont mind about second card.)

1 Spellcaster-Type Tuner + 1 or more non-Tuner monsters.

This card gains 300 ATK for each Spell Counter on it. Each time a Spell Card is activated, place 1 Spell Counter on this card. Once per turn, you can remove 2 Spell Counters from this card to inflict damage to your opponent equal to half this card's ATK.

When this monster attacks a face-down Defense Position monster, destroy the face-down monster immediately with this card's effect. During battle between this attacking card and a face-up Defense Position monster whose DEF is lower than the ATK of this card, inflict the difference as Battle Damage to your opponent's Life Points. If this card battles an Attack Position monster, toss a coin and call heads or tails before damage calculation. If you call it right, destroy the opponent's monster. If you call it wrong, negate the attack and change this card to Defense Position.

(cause l;oads of peple love it)
