"View my deck's combos" - 2 missing combos, and some corrections?

{"ops":[{"insert":"Hello,\nI just found the \"View my deck's combos\" feature, and have been having fun going through my decks to see what it finds. (Thanks very much to the dev team for it!)\n\nI noticed a few combos that appeared to be missing from my Karn-Silver-Golem commander deck - I don't know if this is the right way/place to submit them for consideration, but here's two (that I'm pretty sure work) that should be findable for that deck:\n\nCombo 1:\n\nKarn, Silver Golem + Voltaic Construct + Illusionist's Bracers + [Any mana rock producing 2 mana (Sol Ring, Worn Powerstone, Hedron Archive, etc.)]\n\nSteps:\n1. Equip Illusionist's Bracers to Voltaic Construct.\n2. Use Karn's activated ability targetting an artifact that taps to produce 2 mana (which must have a converted mana cost > 0 or a toughness buff in order to not die when it becomes an artifact creature).\n3. Tap the mana rock for 2 mana.\n4. Pay the two mana to activate Voltaic Construct's activated ability, targetting the mana rock.\n5. Illusionist's Bracers triggers, copying Voltaic Construct's activated ability. Allow copy to remain targetted on the mana rock.\n6. Allow the copy to resolve, untapping the mana rock.\n7. In response, tap the mana rock for 2 mana, left floating.\n8. Allow the Voltaic Construct's original activated ability to resolve, untapping the mana rock again.\n9. Repeat starting at step 3.\n\nEffects:\n- Infinite colorless mana\n- Infinite untap of any artifact creatures\n\nPrerequisites:\n- Mana rock must have a converted mana cost greater than zero, or be under some effect that is buffing its toughness until end of turn.\n\nCombo 2:\n\nKarn, Silver Golem + Voltaic Key + Illusionist's Bracers + [Any mana rock producing 2 or more mana]\n\nSteps:\n2. Use Karn's activated ability targetting Voltaic Key to turn it into an artifact creature.\n1. Equip Illusionist's Bracers to Voltaic Key.\n3. Tap the mana rock for at least 2 mana.\n4. Pay 1 of that mana (leaving the rest floating) to activate Voltaic Key's activated ability, targetting the mana rock.\n5. Illusionist's Bracers triggers, copying Voltaic Key's activated ability. Redirect the copy to target Voltaic Key.\n6. Allow the copy to resolve, untapping Voltaic Key.\n8. Allow Voltaic Key's original activated ability to resolve, untapping the mana rock.\n9. Repeat starting at step 3.\n\nEffects:\n- Infinite colorless mana\n- Infinite untap of any artifacts\n\nPrerequisites:\n- None\n\nIn addition to these two combos, I think I have a couple corrections to offer...\n\nCorrection 1:\n\nI noticed that any combo operating via Voltaic Construct's untap ability seems to include in the Effects:\n\"- Infinite untap of artifact creatures you control\"\nHowever, the card's text (which I verified on Oracle - https://gatherer.wizards.com/DST/en-us/156/voltaic-construct ) says:\n\"{2}: Untap target artifact creature.\"\n, so I think there should be no restriction to artifact creatures *you control* in the Effect list.\n\nCorrection 2:\n\nFor the combo:\nVoltaic Construct + Karn, Silver Golem + Everflowing Chalice\n...there is no mention of a mechanism to keep the Everflowing Chalice alive after it is animated into a 0/0 artifact creature.\nPerhaps something should be included in the prerequisites to indicate this?\n(Furthermore, step 2 says: \"Activate Everflowing Chalice by tapping it, adding at least {3}\"...so it would seem to me like a reasonable prerequisite to mention that the Everflowing Chalice must have at least 3 charge counters on it?)\n\nIn case it helps, my deck which I was exploring when I discovered these suggestions is:\nhttps://archidekt.com/decks/20278875/karn_gated\n\nThank you for your consideration!\n\n-PylonBasicLand\n"}]}
