Is Rebellion's presale a good buy? / Rebellionのプレセールは買いか？

I see that Rebellion has announced a presale.
The presale starts Wednesday, October 18 at 2:00 PM ET / 18:00 UTC and is apparently 5,000 DEC per pack. I wonder if it will sell out soon.

Untamed is 2,000 DEC, ChaosLegion is 4,000 DEC, and now Rebellion is 5,000 DEC.

I think it is too expensive.

Rebellionのプレセールが発表されましたね。
プレセールは、10 月 18 日水曜日午後 2:00 ET / 18:00 UTC からで、1Pack 5,000 DECらしいけれど。すぐ売り切れるかな？

Untamedが 2,000 DEC、ChaosLegionが 4,000 DECと来てのRebellionは 5,000 DEC。

私は高いと思います。

More than Rebellion, I was more interested in the promo cards. I heard that there are two kinds of promo cards this time.
Grimbardun Smith for every 10 packs and Mantaroth for every 100 packs, but buying 100 packs is 500,000 DEC. I don't have that much.

But the card that you get with every 10Pack seems quite useful.
There are 4 skills, so maybe 1 skill each for Bronze, Silver, Gold, and Diamond leagues.

I wonder if it can be used like Lord Arianthus since it has Void and Shield?
Personally, I like Immunity because it has Immunity, which would be useful for the poison rule.

Rebellionよりも、私が気になったのはプロモカード。なんと今回2種類らしいです。
10Pack毎に Grimbardun Smith 、100Pack毎に Mantaroth がもらえるらしいけど、100Pack買うと50万DECですよ？そんなに持ってないよ。

でも、10Packで1枚もらえるカードはなかなか便利そう。
スキルが4つあるからブロンズリーグ、シルバーリーグ、ゴールドリーグ、ダイヤモンドリーグで各1スキルかな？

VoidとShieldがあるからLord Arianthusっぽく使えるのかな？
個人的には Immunity があるから毒ルールの時に便利そうでいいなって思ってます。
