The full version got leaked earlier than usual. (Well, right on time to tell the truth.) So, I decided that I'd transcript the song for those wanting lyrics/translations.

Japanese Transcription:

最強のカードで掴み取れ
輝くデュエル果て無きの夢を

勇気で目覚める奇跡のドラマ
終わることない
ピンチをチャンスに変えてゆこうぜ
きっと出来る

虹の橋を渡り
未来を手に入れろ
Together they fight

扉の向こうに
立ち塞ぐ黒い影
真紅の炎燃やせ

最強のカードで掴み取れ
輝くデュエル果て無きの夢を
どんなにつらい時があっても
信じる仲間の笑顔抱いて

運命を味方につけてゆこうぜ
旅は続く

立ち止まってられない
鼓動を抱きしめろ
Together have a dream

見上げる空には
遥かなる永遠のきらめく明日がある

真実のバトルで探し出せ
心と心の繋ぐ旅を
今こそ僕らは一つになろう
勝利の祈りを胸に刻め

虹の橋を渡り
未来を手に入れろ
Together they fight

扉の向こうに
立ち塞ぐ黒い影
真紅の炎燃やせ

栄光のゴールへたどり着け
消えることない明日へ情熱を
無限大パワーで駆け抜けろ
約束交わした楽園まで

Use your best card to grasp it...
Your shining, endless dueling dream!

Miraculous dramas awakened by courage
They never end.
We're gonna change a dire pinch into opportunity
We'll be able to do it!

Cross the rainbow bridge
and attain your future!
Together they fight

Behind the door
is a dark shadow blocking our way.
Let those crimson flames burn!

Use your best card to grasp it
Your shining, endless dueling dream!
No matter what tough times you're in,
Embrace the smiles of your trusting friends

We're gonna win destiny over to our side.
The journey continues on.

Not going to stand still.
Embrace the beating of your heart closely.
Together have a dream

In the sky overhead...
Lies an eternal, brilliant tomorrow far away.

In a battle of truth, search for it...
A journey connecting our hearts to one another.
Now is the time when we'll be as one.
Carve your prayers of victory on to your heart!

Cross the rainbow bridge

Behind the door
is a dark shadow blocking our way.
Let those crimson flames burn!

Reach the glorious goal!
A passion for tomorrow that'll never die out...
Use your immense, unlimited powers to rush through it!
All the way to the paradise we exchanged promises at!
