Overview
When Whirler Virtuoso enters the battlefield while you control Guide of Souls, Aether Refinery, and Izzet Generatorium, there are two separate "get {E}" events (Whirler’s ETB for {E}{E}{E} and Guide of Souls’s triggered ability for {E}). For each separate event you apply the two replacement effects (Aether Refinery and Izzet Generatorium) in the order you choose, per Ruling [2024-06-07]. Choosing the order that maximizes energy for each event (apply Izzet Generatorium’s "+1" first, then Aether Refinery’s "double") turns Whirler’s 3 into 8 and Guide’s 1 into 4, for a total of 12 energy counters gained. This follows Ruling [2024-06-07] and the energy/get/pay clarifications in Ruling [2024-06-07].
Step 1
Whirler Virtuoso enters the battlefield; this causes two triggered abilities to be triggered: Whirler's "When this creature enters, you get {E}{E}{E}." and Guide of Souls's "Whenever another creature you control enters, you gain 1 life and get {E}." The triggers are put on the stack in the usual order (these are two separate triggered abilities) .
Step 2
When each triggered ability resolves it will cause a separate "you get X {E}" event: one event for 3 {E} (from Whirler) and one event for 1 {E} (from Guide). Replacement effects that modify how many {E} you would get apply to each event separately [Ruling [2024-06-07]].
Step 3
Because both Aether Refinery ("If you would get one or more {E}, you get twice that many {E} instead.") and Izzet Generatorium ("If you would get one or more {E}, you get that many plus one {E} instead.") are attempting to modify the same "get {E}" event, you choose the order to apply those replacement effects for that event [Ruling [2024-06-07]].
Step 4
For Whirler's 3-{E} event: if you choose to apply Izzet Generatorium first, the 3 becomes 3+1 = 4, then apply Aether Refinery to double to 8. If you choose the opposite order, 3 doubled = 6, then +1 = 7. You choose the order (typically to maximize counters) [Ruling [2024-06-07]].
Step 5
For Guide of Souls's 1-{E} event: apply Izzet first then Aether to get (1+1)*2 = 4, or the other order to get 3; you choose the order for that event separately [Ruling [2024-06-07]].
Step 6
If you choose Izzet-before-Aether for both events, Whirler's 3 -> 8 and Guide's 1 -> 4, so you gain 12 energy total. The "get" events are independent, so their replacement-effect ordering is chosen independently for each event [Ruling [2024-06-07]].
Step 7
If you later resolve Aether Refinery’s activated ability ("{T}: You get {E}, then you may pay one or more {E}. If you do, create an X/X ... where X is the amount of {E} paid this way."), the initial "You get {E}" is another separate "get" event and is subject to the same replacement-effect ordering choices at that time [Ruling [2024-06-07]] and payments to pay energy are treated as losing counters per Ruling [2024-06-07] and costs are paid when the ability resolves .
Resolution
If you control Guide of Souls, Aether Refinery, and Izzet Generatorium when Whirler Virtuoso enters, you will get a total of 12 energy counters if you choose the replacement-effect order that maximizes each event (apply Izzet Generatorium then Aether Refinery for each "get" event). This uses the choice-of-order rule for multiple modifiers to energy gains (Ruling [2024-06-07]).
