Synchrostride

Synchrostride ( Arutimetto Sutoraido) is a keyword exclusive to G units.

Characteristics
G units with the "Synchrostride" ability have the following characteristics:
 * They have the red-colored frame with golden lines associated with G units.
 * They have two or more nations, and have all of the clans associated with those nations.
 * They have two or more races corresponding with their nations.
 * They are grade 4 cards. Synchrostride G units with two nations have "Quadruple Drive!!!!" while those with three nations have "Quintet Drive!!!!!".

How It Works
To Stride a G unit with "Synchrostride", for each of that card's nations, you must discard a card with that nation. For example, to Stride "Synchrodragon of Twin Wings, Orbital Beat", which is of the United Sanctuary and Magallanica nations, you must discard a United Sanctuary card and a Magallanica card from your hand. Any of the cards discarded can be Cray Elemental cards.
