Felicio Milson scored after just three minutes to set up Angola for a 3-1 win over Malawi on Tuesday in the final 2027 Africa Cup of Nations matchday two qualifier.
Captain Mabululu doubled the lead on 38 minutes only for Kialonda Gaspar to concede an own goal in first-half added time.
Miro came off the bench in place of Mabululu after 68 minutes and scored three minutes later to seal a Group B victory for the home side.
Overlapping full-backs played a key role in the Angolan victory with a Junior Sambu cross creating the first goal and crosses from Pedro Bondo setting up the other two goals.
Record seven-time champions Egypt and Angola have four points each after two rounds with the Pharaohs first on goal difference. Malawi have three points and South Sudan none.
With Egypt expected to top the final table, the matches between Angola and Malawi are likely to decide who will be the other qualifiers for the 2027 AFCON in Kenya, Tanzania and Uganda.
Angola and Malawi face double-headers during November against South Sudan and Egypt respectively before meeting in Lilongwe next March in the final qualifying round.
Lucky to be only one goal behind at halftime, Malawi came close to equalising just past the hour mark when a close-range shot from Nigeria-born Babatunde Adepoju struck the post.
It was the first competitive win for Angola under Senegalese coach Aliou Cisse, who guided his country to the 2022 AFCON title before a short, less successful stint with Libya.
