Bloom Tender + Derevi, Empyrial Tactician + Emiel the Blessed

Overview
Emiel's {3} activation exiles then returns Bloom Tender, making Bloom Tender a new object when it re-enters the battlefield . Emiel will trigger “whenever another creature you control enters,” and you may pay its triggered ability's {G/W} cost while that triggered ability resolves (you choose whether to pay during resolution) as covered by Ruling [2020-06-23]. However, if Bloom Tender has summoning sickness (it hasn't been under your control since the start of your most recent turn), you cannot activate its {T} ability to produce mana because abilities with the tap symbol cannot be activated while summoning sick . If Bloom Tender is eligible to be tapped (e.g., it was under your control since the start of the turn or it has haste), you may tap it before Emiel's trigger resolves to generate mana to pay the hybrid cost; Bloom Tender produces one mana of each color among permanents you control (and it can't produce colorless) per Ruling [2008-08-01].
Step 1
Start with Bloom Tender, Derevi, and Emiel under your control (same player assumption). Activate Emiel's {3} activated ability targeting Bloom Tender; as that ability resolves it will first exile Bloom Tender and then return it to the battlefield (the exile and return happen during the same ability resolution) .
Step 2
When Bloom Tender returns to the battlefield it is a new object with no memory of its prior existence . Because it is a new object entering the battlefield, Emiel sees 'another creature you control enters' and Emiel's triggered ability triggers for that event.
Step 3
That triggered ability goes on the stack. Before it resolves you get priority and may take actions (for example, cast spells or activate abilities) as normal. If Bloom Tender is eligible to be tapped (i.e., not affected by summoning sickness or it has haste), you may tap it now to produce mana per its oracle text (one mana of each color among permanents you control); Bloom Tender cannot produce colorless [Ruling 2008-08-01].
Step 4
When Emiel's triggered ability resolves you choose whether to pay its {G/W} cost as part of resolution (per Ruling [2020-06-23]); if you choose to pay, you immediately pay the cost and then put the +1/+1 counter(s) on the creature. No player may take actions between paying and the counters being placed [Ruling 2020-06-23].
Step 5
If Bloom Tender has summoning sickness (it hasn't been under your control since the start of your most recent turn), you cannot activate its {T} ability to help pay Emiel's triggered ability because summoning sickness prevents activating abilities with the tap symbol . In that case you must use other mana sources if you wish to pay the hybrid cost when Emiel's trigger resolves.
Resolution
Emiel exiling and returning Bloom Tender makes Bloom Tender a new object when it re-enters . Emiel's triggered ability will trigger and you may pay its {G/W} cost as that triggered ability resolves (Ruling [2020-06-23]). You can use Bloom Tender's {T} ability to produce mana for that payment only if Bloom Tender is actually able to be tapped (i.e., it is not affected by summoning sickness or it has haste) ; if it has summoning sickness, you cannot tap it to help pay Emiel's triggered ability that resolves immediately after it enters. Bloom Tender's mana follows its oracle text and cannot produce colorless mana [Ruling 2008-08-01].
