最高工匠卿、ウルザ

Text:

最高工匠卿、ウルザが戦場に出たとき、「このクリーチャーは、あなたがコントロールしているアーティファクト１つにつき＋１/＋１の修整を受ける。」を持つ無色の０/０の構築物・アーティファクト・クリーチャー・トークンを１体生成する。
あなたがコントロールしているアンタップ状態のアーティファクト１つをタップする：を加える。
：あなたのライブラリーを切り直し、その後一番上のカードを追放する。ターン終了時まで、あなたはそのカードをそのマナ・コストを支払うことなくプレイしてもよい。

Rulings:

• 6/14/2019 The token created by Urza’s first ability will count itself, so it’ll be at least 1/1.
• 6/14/2019 You can tap any untapped artifact you control, including an artifact creature you haven’t controlled continuously since the beginning of your most recent turn, to pay the cost of Urza’s mana ability. Tapping an Equipment this way won’t affect its abilities or the equipped creature.
• 6/14/2019 If you don’t play the card exiled with Urza’s last ability, it remains in exile.
• 6/14/2019 Urza’s last ability doesn’t change when you can play the exiled card. For example, if you exile a sorcery card, you can cast it only during your main phase when the stack is empty. If you exile a land card, you can play it only during your main phase and only if you have an available land play remaining.
• 6/14/2019 If a spell has <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.
• 6/14/2019 If you cast a card “without paying its mana cost,” you can’t choose to cast it for any alternative costs. You can, however, pay additional costs. If the card has any mandatory additional costs (such as that of Lesser Masticore), you must pay those to cast the card.
