I explain the situation that occur in a friend game:
1. First player attacks with red viper
2. knell oasis to give stealth
3. Second player use pentoshi manor and quit stealth and renomb (first players choose go on)
4. First player use a second oasis on red viper.
¿Red viper give or not stealth with the second oasis? im not sure because penthosi read that quit ALL KEYWORDS until the end of phase
