Starting with the creatures, let's talk about Thunderclap Drake , a 2/1 creature with flying for only 2 mana
Transformation : For a cost, typically two generic mana, these tokens can then be transformed at instant speed ( Baby Phyrexians apparently do not care for Summoning Sickness ) into a "Token Artifact Creature - Phyrexian," which retains the previously added +1/+1 counters but now becomes an active participant in combat and other interactions
They're some of the more exciting cards from the set, with Raffine in particular showing up in the best MTG Arena decks for years to come
Sazh Katzroy is a way to tutor what we need, being particularly strong with Sazhs Chocobo, which would already have 3 counters, going to 4 before doubling to 8 (yes, it is a potential 8/9 on turn 4, if there is no removal)
Four mana for a 4/4 reach creature is already a good enough stat line that any red deck will happily play it
