Welcome to the forum, Sol Rei 666, and congratulations on the new deck. Consecrating a divination tool is one of those steps that quietly reshapes everything that follows, so it is worth doing it the right way from the start.
The page you are looking for already exists in full. It is Communicating with the Gods through the TarotExternal ↗, written by High Priest Zevios Metathronos, and it provides the complete procedure for consecrating a Tarot deck in a formal ritual dedicated to Zeus so the cards "speak the truth" during readings. The procedure is simple and complete: stand before your altar, invoke Zeus, light a white candle, hold the deck and visualize the power of Zeus infusing it, then speak words of blessing. High Priest Zevios gives you sample wording on the page, but he also tells you to "speak from the heart" if that resonates more. The ritual closes with a final invocation or prayer of thanks to Zeus. That is the whole working, and you should do it exactly as written rather than building a custom version.
On your specific request for runes and affirmations, here is the honest answer: the published Tarot ritual does not prescribe a particular set of runes to vibrate during consecration, and that is deliberate. The rite uses your own devotional words as the affirmation, so there is no script to copy and no rune selection to import from a deity-specific ritual. If you tried to reverse-engineer something from a God ritual or from the Consecrating and Empowering Ritual ToolsExternal ↗ page, you would be inventing a custom working, and the Temple guidance on consecration is meant to be followed as published, not patched together from different sources. The Clergy's general tool consecration page is a great conceptual reference for why a tool must be purified and dedicated in Zeus's name, but it is not a second Tarot ritual and should not be combined with the Tarot one. You will notice both pages agree on the core principle: speak with intent, dedicate the tool to the Gods, and let it accumulate power through real use.
On the "helping others" part, this is where you need to read the ritual closely. The deck, once consecrated, is a personal sacred tool. The page is very clear that it "must not even be touched by other people, let alone non-Zevists." That does not mean you cannot read for others. It means you remain the one shuffling, laying out, and interpreting the cards, while the person you are reading for receives the message through your voice. This is actually how most professional readers in many traditions operate anyway: the deck stays with the reader, the querent listens. So your wish to help others is fully compatible with the ritual, as long as you keep the deck on your own hands. For background on why this matters, the general consecration pageExternal ↗ explains that "other people should not handle your consecrated tools" because the energy signature of the tool is keyed to you and to the Gods, and allowing others to handle it can introduce conflicting energies that weaken the consecration.
If you want to understand the runic system in case the words of power path calls to you later, The Runic KabalahExternal ↗ is the right starting point, with Using the RunesExternal ↗ as the practical guide by High Priest Zevios Metathronos. Those pages show how vibrating syllables of power with breath and affirmation works in this tradition, and they are useful reading to grow into. But for the deck itself, the Tarot ritual is the entire consecration. No extra layer is needed.
A small practical note. When you do the ritual, treat it as a real conversation with the Gods rather than a recitation. Light the white candle, take a few slow breaths, invoke Zeus in whatever words feel true to you, then speak the blessing over the deck. The sample wording on the page covers exactly the themes that matter for a divination tool: truth, divine will, wisdom, and guidance to the Initiate. If you add anything of your own, keep it short and sincere. After you close the ritual, the deck is ready. From then on, before each reading, pray to your Guardian Daemon through Zeus as the page describes, and the deck will do its work.
Once you have done the consecration, come back and tell us how the deck feels in your hands. The first few readings after a fresh dedication are often the ones that surprise you the most, and the community here benefits from hearing about real experiences with sacred tools.
Hail Zeus, and welcome to the path.
