Asmodeus the Archfiend + Necrotic Ooze + Skirge Familiar

Overview
If Necrotic Ooze is on the battlefield and Asmodeus the Archfiend and Skirge Familiar are in a graveyard, Necrotic Ooze will gain the activated abilities printed on those creature cards (for example, Asmodeus’s “{B}{B}{B}: Draw seven cards.” and “{B}: Return all cards exiled with Asmodeus…” and Skirge Familiar’s “Discard a card: Add {B}”). Necrotic Ooze does not gain Asmodeus’s replacement/static ability “If you would draw a card, exile the top card of your library face down instead.” because that ability is not an activated ability (activated abilities contain a colon) [Ruling [2011-01-01]]. Skirge Familiar’s discard-to-add-{B} is a mana ability and does not use the stack, so Necrotic Ooze can use it to produce the black mana needed to pay for Asmodeus’s {B}{B}{B} draw activation [Ruling [2021-06-18]].
Step 1
Ensure Necrotic Ooze is on the battlefield and Asmodeus and Skirge Familiar are in graveyards so Ooze has the activated abilities printed on those creature cards.
Step 2
If you need black mana to pay for Asmodeus’s {B}{B}{B} activation, activate the gained Skirge Familiar ability by discarding a card to add {B}; because that is a mana ability it doesn’t use the stack and produces {B} immediately [Ruling [2021-06-18]].
Step 3
Repeat the discard-to-add-{B} activation as needed (or produce the remaining mana by other means) until you can pay {B}{B}{B} for Asmodeus’s gained activated ability.
Step 4
Activate the gained Asmodeus ability “{B}{B}{B}: Draw seven cards.” Pay costs, put the ability on the stack, and let it resolve; when it resolves you draw seven cards normally (Oo ze did not gain Asmodeus’s replacement ability, so draws are not replaced by exiling) [Ruling [2011-01-01]].
Step 5
If you also activate the gained Asmodeus {B}: Return all cards exiled with Asmodeus to their owners’ hands, it will return only cards that were exiled by an actual Asmodeus static/replacement ability; in the normal Ooze-activated-draw case there are none to return.
Resolution
With Ooze on the battlefield and Asmodeus + Skirge Familiar in graveyards, Ooze can activate Skirge Familiar’s discard ability (a mana ability) to generate {B} and can use that mana to activate Asmodeus’s gained {B}{B}{B}: Draw seven cards ability. Those draws are normal draws (the Asmodeus replacement effect is not present on Ooze), so cards are not exiled and Asmodeus’s {B} return ability (if also gained by Ooze) will return nothing. Be aware that drawing from an empty library will make you lose the game and that returning cards and losing life could cause you to lose the game if your life total becomes 0 or less .
