Dark Tower

[Zyzzyzus]

Not sure if there has been another set of Dark Tower cards, I am making my own set anyway.

Returns to the owner's hand during the End Phase of the turn that this card is Summoned or flipped face-up, this effect cannot be negated. You can Special Summon this card from your hand or Graveyard if you control "Maturin of the Beam". Any card effect that would destroy other monsters you control, except "Maturin of the Beam", instead affects this card. If a monster leaves the field, Tribute this card and Special Summon that monster to your side of the field (this is not optional). That monster cannot be used to Summon another monster.

*This is the original Guardian, not the cyborg, but he's still named Shardik.[/spoiler]

Returns to the owner's hand during the turn this card is Summoned or flipped face-up. You can Special Summon this card from your hand if you control "Shardik of the Beam", by Tributing it and 1 other monster you control. Once per turn, you can Special Summon 1 Level 6 or lower monster from your Extra Deck, and you can attach "Shardik of the Beam" from your Graveyard to an Xyz Monster Summoned with this effect as an Xyz Material. "Shardik of the Beam" cannot be Special Summoned this turn if you activate this effect.[/spoiler]
