Legendary Duelists - LED8 - Synchro Storm

If only your opponent controls a monster, you can Special Summon this card (from your hand). You can only Special Summon Unknown Synchron once per Duel this way.

During damage calculation, if a Warrior Synchro Monster you control battles an opponent's monster (Quick Effect): You can send this card from your hand to the GY; your battling monster's ATK becomes double its current ATK during that damage calculation only. You can banish this card from your GY, then target 1 Synchron monster in your GY; add it to your hand. You can only use each effect of Rush Warrior once per turn.

If this card is in your hand: You can destroy 2 other monsters in your hand and/or face-up on your field, including a WIND monster, and if you do, Special Summon this card, and if you do that, and both destroyed monsters were WIND, you can also banish exactly 4 cards from the top of your opponent's Deck. If this card is destroyed by card effect: You can add 1 non-WIND Wyrm monster from your Deck to your hand. You can only use each effect of Mariamne, the True Dracophoenix once per turn.

1 Tuner Synchro Monster + 1+ non-Tuner Synchro Monsters
If your opponent would Special Summon a monster(s) (Quick Effect): You can Tribute this card; negate the Summon, and if you do, destroy that monster(s). During the End Phase, if this effect was activated this turn (and was not negated): You can Special Summon this card from your GY. If this card is destroyed by battle, or if this face-up card you control leaves the field because of an opponent's card effect: You can Special Summon 1 Level 8 or lower Warrior Synchro Monster from your Extra Deck. (This Special Summon is treated as a Synchro Summon.)

1 Tuner + 1+ non-Tuner monsters
When this card is Synchro Summoned while you control no other monsters: You can target 1 Junk monster in your GY; Special Summon it. You can only use this effect of Stardust Assault Warrior once per turn. If this card attacks a Defense Position monster, inflict piercing battle damage.

2 Level 3 WIND monsters
When a Spell/Trap Card is activated (Quick Effect): You can detach 2 materials from this card; negate the activation, and if you do, destroy it. This card loses 300 ATK while it has no materials.

2 Level 4 monsters
Once per turn (Quick Effect): You can detach 1 material from this card, then target 1 Spell/Trap on the field; destroy it.

Target 2 WIND monsters in your GY and 1 card on the field; shuffle both of those first 2 targets into your Deck, and if you do, return the other to the hand.
